I'm not sure this is what you are looking for, but within the next 18 months DiscoTest will have pre and post data for over 1000 students in grades 4-12, with many thousands to follow. The raw data are written responses, which have been scored with a new low-inference rubric system in which each selection on a given rubric represents a highly specified way of thinking about a specific topic. Each rubric selection is located in a specific position on a general developmental scale.
The highest scores on these rubrics are used to calculate a developmental score. But there is a more complex story to tell about student performance, because taken together, rubric scores tell a rich story about how a given student understands and operates on knowledge in the area targeted by the assessment. We are interested in modeling this complexity.
We will be interested in developing partnerships with professors who work with graduate students who may be interested in:
- developing score algorithms
- testing rubrics
- modeling patterns in performance in various groups of students
- publishing their work
DiscoTests are produced by a nonprofit organization that provides free online assessments and learning resources to teachers and students.

If there is such a data set I would like to get it too!

I would like it also, so I could look at the order of hierarchical complexity of the items and what subtasks that have to be addressed. I need the actual items and not just their scores.

I am interested in locating large item pools containing individual responses to achievement or aptitude questions (e.g. math achievement test data for students in grades 1-3). Optimally the data set(s) would already include the item difficulties calibrated using the original sample, but that is not a requirement.

Our mission is to develop standardized, formative, and diagnostic developmental assessments of the knowledge and skills required to meet the challenges of the 21st century. Our aims are threefold: (1) to build engaging, educative, and feedback-rich developmental assessments and learning resources for K-18 students and their teachers, (2) to create equally rich assessments that diagnose learning needs and support the development of adults (in the workplace and beyond), and (3) to build (and share) knowledge about learning and its role in the future of society.
