Grader III Details

GRADER III is a flexible instructional assessment system combining grade-keeping, test and item analysis, and email feedback to students.

The GRADER III system can maintain class records including performance ratings, class projects, essay exams, or objective-type exams. Student objective test responses can be scanned, scored, and entered into the GRADER III system.

Test Analysis

The Scoring Office provides a test analysis service that can be requested as part of the GRADER III system, but it isn’t necessary to use GRADER III in order to receive a test analysis. The Scoring Office’s test analysis can provide:

  • Lists of student scores in name order
  • Lists of student scores in PID order
  • Lists of student scores in percentile rank order
  • Test score means and standard deviations
  • Percentile ranks associated with each raw score
  • Standard scores associated with each raw score
  • Frequency distributions of raw scores
  • Histograms of test raw scores

Item Analysis

The Scoring Office also provides item analysis that can be requested as part of the GRADER III system. It can also be requested for independent objective tests that are scanned and scored.

Item analysis provides useful information for evaluating objective tests and helps instructors identify quality test items that are of appropriate difficulty and discriminate between different levels of student proficiency. Item analysis from the Scoring Office includes:

  • Division of the test group into high, middle, and low scoring groups
  • Complete tabulation of responses to an item (long form)
  • Brief tabulation of responses to an item (standard form)
  • Item index of difficulty (proportion wrong or proportion right)
  • Item index of discrimination
  • Summary of item difficulty over all items
  • Summary of item discrimination over all items
  • Estimates of reliability

For a more detailed description of item analysis, see the MSU Scoring Office’s publications Introduction to Item Analysis and Interpreting the Index of Discrimination.

Email Feedback

The Scoring Office can distribute GRADER III Feedback reports to students’ MSU email. Feedback reports are produced for individual students by the GRADER III system when an objective test is scanned and processed.

The feedback report indicates the student’s answer to each item and the correct keyed response, if the student’s response was incorrect. In addition to the current objective test score, this report shows a cumulative report of the student’s scores in the course, whether they are test scores, essay grades, performance ratings, or term paper ratings.

The GRADER III system refers to student performance entries as Test 1, Test 2, through Test 24. Students will need some assistance in keeping straight the GRADER III entries which appear on either printed or electronic feedback reports.

It is strongly suggested that instructors provide their students with a GRADER III to class assignment conversion table. Here’s an example:

Assignment Conversion

 Grader III Test     Class Assignment
 Test 1  Hourly Quiz 1
 Test 2  Homework Exercise
 Test 3  Midterm Exam
  …   …
 Test N  Final Exam

An assignment conversion table could be handout, included in the syllabus, or on a course web page to help avoid student confusion.

How Email Feedback Works

Email Feedback must be based on a GRADER III account with records pulled from the current Registrar’s class list for authentication. This is the normal method of establishing a GRADER III account.

GRADER III produces a file of feedback reports for students whose PID and first two letters of their last name agree with the current Registrar’s class list.

If a student record fails the authentication process, this information is included in the feedback report emailed as an attachment to the instructor. This attachment has the file specification FEED####.TXT, where the four numbers reflect the instructor’s GRADER III account number. The most common reasons for authentication failure are an incorrectly marked PID or name on the student’s answer sheet.

The Scoring Office sends email feedback to students via the PIDMail system. PIDMail produces a list of PIDs to which feedback reports were emailed. A copy of this list is also emailed to the instructor.

GRADER III emails feedback reports to each student’s MSU email. (If needed, the MSU IT Service Desk provides information and support for MSU email.)
