Test Scoring and Analysis

Need reliable, accurate, secure test scoring with 24-hour turnaround? If you teach regularly scheduled credit courses on the West Lafayette campus, you can use our free Instructional Data Processing service.

IDP offers a free test scoring and analysis service for objective, multiple-choice examinations on the West Lafayette campus. The service provides high levels of reliability, accuracy, and security with a 24-hour turnaround time.

All information and materials needed for the service, including the free machine-readable student response forms, can be obtained from IDP in Room G-39, Stewart Center. Response forms should also be returned to G-39 for scoring and analysis.

Available machine-readable answer sheets

IDP-1 has one hundred fifty items with five responses each (available in four colors).

IDP-11 has thirty items with five responses each (available in two colors).

IDP-2 has one hundred items with ten responses each (available in brown).

IDP-3 has fifty items with five responses each (available in orange). These sheets also have space for up to fifteen hand-graded items to be included in the scoring. The points assigned for the hand-graded items must be written in and gridded in as three-digit whole numbers.

IDP-15 has six items with five responses each (available in two colors).

The test scoring package offers many scoring and reporting options that make it possible to grade everything from an attendance or short quiz to a lengthy final exam. Scoring procedures can include item weights, either-or scoring, converting raw scores to percentages, etc. You may even have your students' scores sent directly to Blackboard or receive an electronic copy via Filelocker.

You can order student score reports and statistical summaries that provide information about student performance.  Student performance reports also may be sorted in a number of ways to help assign grades and maintain class records. For example, instructors can use data in the Score Distribution report to establish grade cutoffs, while the Item Analysis report helps instructors assess the level of test item reliability. 

Instructors must complete a "Request for Test Scoring Service" worksheet each time they need to have a test scored. This worksheet outlines the scoring and reporting options available and allows instructors to tailor the service to their individual needs. 

Using Blackboard Learn or Filelocker

IDP can send scores directly to Blackboard Learn.    You provide us with an IDP job number when the test is dropped off for scoring and within 24 hours the scores will appear in your Blackboard Learn grade book.   Don’t worry; they are not visible to students at this point.  You choose when your students will see the scores.   A score will not go to Blackboard if a student does not use their correct PUID.  We will provide at your request, however, a paper copy that will contain all scores. 

Not using Blackboard?  IDP can send scores to you electronically via Filelocker in a file that is easily opened in Excel.  Easy to read instructions may be found on the Filelocker website.   It is IDP policy and against FERPA regulations to e-mail score files to you.

Course Records Management System (CRMS)

IDP offers a Course Records Management Service (CRMS) to help faculty maintain their class grade book for the entire semester in one location. CRMS makes it easy to store and report semester totals and grades.  In addition, hand-graded data or online scores can be easily added to an instructor’s IDP stored grade book by submitting those items to IDP in Excel format.

Once the data is stored, the instructor can request set weights for the various grading components, drop or add scores, scale groups and assign letter grades.  Entire grade books can be uploaded to Blackboard to allow for an easy grade push by the instructor.

Scanning Services

Instructional Data Processing (IDP) utilizes a high-speed optical page scanner that collects data from machine-readable student answer sheets. Once the forms are scanned, the student responses are stored in a computer data file.  IDP then manipulates the electronic response file to provide customers with a wide range of custom data analysis. 

IDP has several types and sizes of answer sheets available, which can be adapted to a variety of data collection tasks. For users with more unique requirements, Scantron Corporation can assist in the design and development of custom answer sheets.
