I am looking for a publicly available data set of (ideally) the following kind.

 1. Multiple (must be 3 or more) examiners each grade the academic
    work (e.g., essay, dissertation, term-assignment) of multiple
    (ideally 20 or more) students.
 2. Every examiner grades every student.
 3. In addition to the grade given by each examiner to each student,
    there is a single "comprehensive" grade for each student given by
    faculty, based (in some manner that is transparent) on the other
    grades.

An example might be where all Honors-level dissertations are marked by the four members of a faculty examining committee.  The description is of an ideal example, but I'd be very pleased to learn of other similar open-data examples where the grade involves some degree of "judgement" on the part of the examiner. I'm not looking, for example, for a dataset where multiple people ("examiners") record their reading from a measuring instrument (i.e., give a grade) under multiple conditions (equivalent to "multiple students")
