Thesis and Dissertation Policies and Practices

Students depositing their thesis (or dissertation) with the Purdue University OGSPS must certify that they have prepared the thesis while observing the provisions in Purdue University Policy III.A.2, November 18, 2011, Policy on Research Misconduct. Students will make the appropriate selection using the Form 9 Electronic Thesis Acceptance Form.

Thesis Copyright Protection

Purdue University Policy I.A.1, May 18, 2007, Intellectual Property, established that copyright ownership now resides with you, the author. The copyright symbol © is not required for works to be copyrighted. All candidates have the additional option of applying for registration of their copyright. This establishes a public record of theses/dissertations and confers additional legal rights, enabling individuals to file infringement suits and seek statutory damages as well as attorneys’ fees. Copyright registration can be filed here.

Specific questions regarding your rights and responsibilities under U.S. copyright law may be addressed to the Purdue University Copyright Office.

Using Material Protected by Copyright

Purdue University promotes compliance with U.S. copyright law and understanding of the appropriate use of copyrighted works: Purdue University Policy I.A.3, January 1, 2015 Use of Copyrighted Materials for Educational and Research Purposes.

When quoting extensively from copyrighted material, the author must obtain written permission from the copyright holder. There is no precise relationship between the amount of text quoted and the requirement for written permission to use the material. The law governing copyright infringement is based on the fair use principle. Ordinarily, if you plan to quote more than 150 words of continuous text from copyrighted material, you should ask permission from the author. If the work you are quoting has significant commercial value, you should obtain permission to quote any complete or nearly complete text item or section. When your quotation of copyrighted material could have a negative impact on the existing commercial value of that material, obtain the copyright holder’s permission. Figures or other graphical material, including Web pages, should not be reprinted in your thesis without the author’s consent. Permission to use copyrighted material is usually granted on condition that acknowledgment is made.  You will be responsible for any required payments.

You will be required to upload copyright permissions to HammerRR (Figshare) when depositing your thesis with the Purdue University OGSPS. However, private personal information in copyright permissions, such as a home address, personal phone number, and personal email address, should be redacted. You should retain the original unredacted permissions for your records.

By depositing a thesis with the Purdue University OGSPS, you certify that all copyrighted material incorporated into the thesis complies with United States copyright law and that you have received written permission from the copyright owners for the use of their work, which is beyond the scope of the law. You also agree to indemnify and save harmless Purdue University from any and all claims that may be asserted or that may arise from any copyright violation.

Data subject to EAR, ITAR, DFARS Clause 252.204-7012, Controlled Unclassified Information (CUI), Covered Defense Information (CDI), or other controlled data designators require increased security to establish compliancy with government regulations. Due to these increased security requirements, an alternative deposit process method is required to be followed for controlled theses and dissertations. Please review all information in the Thesis Requirements web page. Please also refer to additional information outlined within the Guidance Document – Controlled Thesis Submission Process.

Publication of the thesis or dissertation is a required part of the deposit process. The university currently uses HammerRR to publish the thesis, after which your thesis will become an Open Access document with no additional cost to you.

All theses and dissertations submitted to a designated Purdue repository are considered the final copy and are required to be in acceptable formatted condition. After your deposit is submitted, a Thesis & Dissertation Office staff member will review your deposit. For more information, please review the Deposit Process steps outlined in the Thesis Requirements web page.

To further promote and preserve the intellectual contributions of its degree recipients, Purdue is also partnering with ProQuest / Clarivate to disseminate its emerging scholarship through the ProQuest Dissertation & Theses Global and Web of Science databases, which reaches thousands of institutions and millions of researchers worldwide. ProQuest also partners with major search and discipline-specific indexes for additional amplification and provides all of these services free of charge. By distributing your work with ProQuest, you will increase its visibility and impact within the global research community.  ProQuest recognizes the critical importance of embargos and will never publish a thesis until it has been released for dissemination by the university. You may withdraw your work from distribution at any time. You are eligible for a 10% royalty based upon sales and usage of the full text of the work. Please contact disspub@proquest.com with any questions and to set up your account to collect royalties.

Open Access Theses and Dissertations

Each student grants, without restriction, royalty free to Purdue University the nonexclusive right and license to reproduce, distribute, and display, in whole or in part, all theses and dissertations in any format now known or later developed for preservation and access in accordance with this agreement and will be made to the general public at no charge.

Benefits of an Open Access Thesis or Dissertation:

[1] Higher Citation Rates

The more users who can access a work, the more researchers that can cite that work.

[2] Better Global Visibility of Your Work

By making their work globally visible through open access, authors are allowing more scholars, more promising students and future scholars, less wealthy institutions, policy makers, news reporters, and the unexpected reader and citizen scholar to have access to their work who may not have otherwise had the ability or funds to access closed-access scholarship.

[3] Meeting the Land Grant Mission of the University

“Open access at Purdue can publicly showcase the scholarly output of the University and its community members, this provides greater visibility and traffic to your department, school, and ultimately the university. It can also show that scholars and researchers at Purdue think beyond their own disciplines by showcasing the interdisciplinary scholarship and research being created at Purdue. Finally, open access scholarship demonstrates accountability to the public that funds the university, while disseminating knowledge gained and created at Purdue; satisfying the public, land-grant mission of the university.”

Students are REQUIRED to use an official Purdue University Thesis Template to write their thesis/dissertation and ensure proper formatting requirements are met.

A thesis authored at Purdue University should be structured using one of the below methods:

Traditional

A traditional thesis is a document that provides a complete and systematic account of your research. A typical traditional thesis suggests the following structure:

• Preliminary pages
  • Title page
  • Statement of Approval page
  • Dedication (optional)
  • Acknowledgments (optional)
  • Table of Contents
  • List of Tables
  • List of Figures
  • Abstract
• Main Body pages (required)

  • Methods
  • Results
  • Discussion
  • Conclusions and Recommendations
• Back Matter pages
  • Appendix (optional)
  • References
  • Vita (optional)
  • List of Publications (optional)

* Thesis structure may vary by department. Please consult your committee for specific departmental requirements.

Article-based

An article-based thesis is a collection of published (or will be published) research articles consisting of an introductory and concluding chapter. A typical article-based thesis suggests the following structure:

• Preliminary pages
  • Title page
  • Statement of Approval page
  • Dedication (optional)
  • Acknowledgments (optional)
  • Table of Contents
  • List of Tables
  • List of Figures
  • Abstract
• Main Body pages (required)
  • Introduction
  • Published Article #1
  • Published Article #2

  • List of Publications (optional)

* Thesis structure may vary by department. Please consult your committee for specific departmental requirements.

Theses authored using this structure will need to include acknowledgement of prior publication within the respective chapter. Although each journal may have specific statement requirements, the acknowledgment should be single spaced and appear under the chapter title. For additional information and examples of publication citation references, please review templates and handbooks in the Templates website.

Creative work

OGSPS is prepared to accept theses in creative formats subject to departmental and committee approval. Students wishing to submit a creative work as their thesis requirement should consult with their committee chair and contact the Thesis & Dissertation Office with their proposal.

WCAG 2.1 Level AA Compliance
Last Updated: 05/13/2026

Beginning Spring 2027, all theses and dissertations deposited with Purdue University must comply with the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA standards.

This requirement ensures that graduate research is accessible to individuals with disabilities and aligns with federal accessibility obligations.

Student Responsibility

Students are responsible for ensuring that their thesis or dissertation file is fully accessible prior to submission. This includes verifying that all required accessibility elements are present and that the document passes an accessibility check before it is deposited.

Submissions that are reviewed and found to be non‑compliant with WCAG 2.1 Level AA standards will be returned to the student for correction. Accessibility compliance is required for final acceptance.

What This Means for Your Submission

To meet WCAG 2.1 Level AA requirements, your thesis or dissertation must be created using accessible authoring practices, such as:

• Headings. Your thesis or dissertation must use built‑in heading styles (for example, Heading 1, Heading 2, Heading 3) to show the structure of the document. Headings are not just visual formatting. They create a navigable outline that screen‑reader users rely on to move through your work.
• Color Contrast. All text, charts, graphs, and figures must have enough contrast between foreground and background colors so they can be read by users with low vision or color‑vision deficiencies. For normal text, WCAG 2.1 Level AA requires a contrast ratio of at least 4.5:1 between text and its background. Color should never be the only way information is conveyed.
• Alternative Text. All meaningful images, including charts, graphs, diagrams, and figures—must include alternative text (alt text) that describes the information the image conveys. Complex images require a two‑part text alternative. The first part is a short description that identifies the image and, when appropriate, directs readers to the long description. The second part is the long description itself, which explains the key information the image communicates.
• Accessible Tables. Tables must be created using Word or LaTeX’s built‑in table tools, not by using tabs, spaces, or images of tables. Tables should have a simple, logical structure, with clearly identified row and/or column headers so screen readers can correctly associate data cells with their headers.
• Logical Reading Order. The logical reading order must be manually checked to ensure that a screen reader will read content in the same order a sighted reader would expect. If your final submission is a PDF, it must be a tagged PDF. Tags provide the underlying structure (headings, paragraphs, lists, tables, figures) that assistive technologies use to read the document correctly.
• Selectable Text. All text in your thesis or dissertation must be real, selectable text, not scanned images of text. Screen readers cannot read scanned text unless it has been properly converted using OCR, and OCR errors often make documents inaccessible.

Recommended Tools for Checking Accessibility

Before depositing your thesis/dissertation, students must ensure that their document meets current ADA accessibility requirements using the following tools when preparing their document:

• Microsoft Word Thesis Template users: Students are required to check their thesis/dissertation for accessibility compliance and resolve all outstanding accessibility issues using the built-in accessibility checker. You can learn more about the accessibility checker from the Microsoft Accessibility page.
• LaTeX/Overleaf Thesis Template users: Students are required to check their thesis/dissertation for accessibility compliance using Adobe’s built-in accessibility checker and resolve all outstanding accessibility issues. For more information, review Adobe’s Accessibility information.

Running these checks early and addressing issues throughout the writing process will help avoid delays at the time of deposit. However, automated accessibility checkers are not sufficient for confirming compliance. Manual checks are still needed to ensure that the thesis or dissertation file meets all WCAG 2.1 Level AA standards including color contrast requirements and logical reading order.

Timing and Impact on Graduation

Accessibility compliance is a required component of the thesis and dissertation deposit process. Students should plan adequate time to address accessibility issues before their final submission deadline. Failure to submit an accessible document may delay acceptance of the thesis or dissertation and could impact graduation timelines.

Additional Support

Students are encouraged to review these materials early in the writing process.

• Purdue Innovation Learning offers workshops and resources to aid students with document and content accessibility.
• The Assistive Technology Lab (ATL) provides assistive technology resources to support faculty, staff, and students with accessible information access and computing.
• Purdue Libraries offers a Digital Accessibility Skills Resource Guide to support the creation of accessible digital content.
• FAQs and accessibility resources are available on the ADA Title II Compliance FAQs webpage provided by Innovative Learning at Purdue University.

If the primary literature on a subject matter is in a language other than English and the thesis or dissertation addresses a community of scholars who publish in a language other than English, a student may elect to write the thesis in a language that all committee members speak and read and support its use in the thesis. In this case, the thesis should contain a title page and abstract page in English.

All West Lafayette, Purdue Indianapolis, Purdue Fort Wayne, and Northwest candidates are required to submit the Form 9 ETAF through their Graduate Student Portal dashboard after passing the final defense/exam and receiving exam form approval signatures by the student’s exam committee.

Effective September 1, 2014, Purdue’s OGSPS requires that all theses and dissertations be reviewed using the iThenticate software and any issues identified by the software addressed prior to the deposit of the final thesis or dissertation with OGSPS. Non-controlled theses/dissertations must be submitted through iThenticate and receive a satisfactory pass result prior to the student’s thesis Chair certifying the results in the student’s Form 9 ETAF. Controlled theses/dissertations CANNOT be run through iThenticate, or any other plagiarism checker or AI tool, until AFTER both the Thesis & Dissertation office and the Purdue Research Security and Export Controls (RSEC) team have received acceptable documentation from the student’s sponsors that authorize its release and publication. Satisfaction of this requirement will be certified by both committee chair and degree candidate on the ETAF. Click here for more information.

Embargo

Non-controlled theses/dissertations: Students who wish to delay public release of their thesis or dissertation must make the appropriate selection on the Form 9 Electronic Thesis Acceptance Form (ETAF) and make the same embargo selection when depositing to HammerRR. Embargo periods are 6 months, 1 year, or up to a maximum of 2 years. The embargo information that is provided in the ETAF and HammerRR will be validated for consistency at the time of your deposit submission. If inconsistencies are present between the ETAF and HammerRR, the HammerRR selection will be updated by administrators to match what you have selected and approved in the ETAF. During the embargo period, the HammerRR metadata (which includes the Abstract) will be publicly available for viewing; however, the thesis/dissertation document will remain unpublished and inaccessible until after the embargo period has expired. Students may embargo their thesis when applying for patents, have publications pending, or when proprietary rights are involved.

Confidentiality

Non-controlled theses/dissertations: Students whose thesis/dissertation content is subject to a confidentiality agreement, contains proprietary rights, and/or is included in patent applications may select a confidentiality period of 6 months, 1 year, or up to a maximum of 2 years. Theses and dissertations are deposited to HammerRR. During the confidentiality period, both the HammerRR metadata and the thesis/dissertation document remain unpublished and inaccessible until after the confidentiality period has expired.

Controlled theses/dissertations: Students whose thesis/dissertation content is subject to EAR, ITAR, DFARS Clause 252.204-7012, Controlled Unclassified Information (CUI), Covered Defense Information (CDI), or other controlled data, and/or have certain contracts on file with Sponsored Program Services (SPS), are required to select an indefinite confidentiality period and must include their Technology Control Plan (TCP number), sponsor information, secure locations of stored thesis/dissertation, and secure locations of research in the Form 9 Electronic Thesis Acceptance Form (ETAF). Controlled theses/dissertations CANNOT be shared virtually or electronically, submitted through iThenticate or any other plagiarism checker or AI tool, or be submitted to HammerRR. Instead, controlled theses/dissertations must be deposited in a designated secure non-public repository. Students must email the Thesis & Dissertation office at thesishelp@purdue.edu as early in the semester as possible to notify staff members that their thesis or dissertation contains controlled content and to request controlled thesis deposit requirements information.

Please visit the Thesis Requirements website for important information pertaining to thesis and deposit process requirements.

Candidates are required to meet both departmental and OGSPS deadlines each term. Please refer to the Graduation Dates and Deadlines calendar for important semester deadlines.  Because there are two different types of candidacy registration (CAND 99200 and CAND 99100), there are two different sets of deposit deadlines.  Students must adhere to the correct deadlines based on their candidacy registration. 

Contact the Thesis & Dissertation Office for questions.

• Survey links will become available in the student’s Graduate Student Portal dashboard during the semester in which they register as a candidate for graduation.  The following must be completed prior to depositing the thesis or dissertation:

• Dissertation Fee: $125.00

Purdue West Lafayette and Indianapolis Campus:
Purdue West Lafayette and Indianapolis candidates will be billed through their myPurdue accounts within 10 business days.

Purdue Northwest and Purdue Fort Wayne Campuses:
Purdue Northwest and Fort Wayne candidates will be billed through their campuses and students must pay the deposit fee through their campus Bursar’s office.

OGSPS expects candidates and departments to thoroughly review format and content of theses and dissertations prior to their electronic submission. OGSPS does not generally permit post-facto revisions to Electronic Thesis Deposits (ETDs) once they have been accepted and approved for deposit by the Thesis & Dissertation Office. Post-facto edits are only permitted to correct significant textual, data, or mathematical errors affecting accuracy of content and which could be potentially embarrassing to Purdue University.

Exceptions to OGSPS policy will be considered on a case-by-case basis and may be requested by submitting a letter with justification for the exception to OGSPS for consideration. Requests must be endorsed by the student’s major professor and the Head or Chair of the Graduate Program. OGSPS may require additional approvals if the request may impact other offices within the University (see Section VII.I of the University Catalog).
