Service Rules

• Service Support Staff will not alter a student's (or respondent's) bubble sheet under any circumstances.To do so would compromise the integrity of the exam (or survey) and the student's appeal process.
• A Service Support Staff Supervisor will only correct scanned data results or the exam answer key with explicit written instructions from the instructor.
• For security reasons, OMR sheets must be delivered by hand to the ITS OMR Service located at 70 Arts Building. The sheets will be signed in by the OMR support staff.
• For security reasons, OMR sheets must be picked up by hand from the ITS OMR service located at 70 Arts Building. The sheets must be signed out by the instructor or College/Department representative who must present photo ID.

• It is the responsibility of the instructors or Colleges/Department representative to pickup the OMR sheets within 72 hours of completion of processing.

Service Caveats

The scanning system can only indicate whether the scanning hardware determines a bubble is filled in above a threshold. Similarly, the scanning hardware must determine whether a bubble has been erased completely enough to fall below the threshold. The system cannot determine a student's intent. An instructor inspecting a student's bubble sheet might also have trouble deciding what the student intended. However, the scanning system ignores any other markings on the form and does not indicate whether a determination was marginal or not.

The threshold can change over time, meaning that it is possible that scanning the same sheet on different occasions might return slightly different results. If bubble are filled in carefully and completely (and erased thoroughly) then the likelihood of different results is greatly reduced. It is similarly possible that different instructors reviewing the same form might interpret the student's intent differently.

Only forms marked with HB pencil scan reliably. Pens or markers do not scan reliably. Harder pencils do not erase sufficiently. Forms are rejected by the scanning system only in a few cases—the student number scanned is incomplete or inconsistent or if multiple responses are observed for any question. Otherwise misinterpretation of a student's responses will go unreported.
