Dan,

The 40,000 subjects is total across the grades - I also have district level
data (from another district of 24,000), in which the tests were designed to
be of increasing difficulty as the grade levels rose. This data is in
Reading and Mathematics as well. I will be contacting both of these
districts to see if they will allow me to release this old data (the data is
from the mid-to-late 90s) but all the items have been calibrated as well
resulting person scores. The second set of scores go from first through
eighth grade, while the first set of scores go from second through sixth
grade. Which do you think would be most appropriate for your needs?

Bob,

   Thanks for your help.  40,000 subjects is a good size for me.
Confidentiality should not be a problem.  Other than the item-level
achievement data, I'd only need age and/or grade level and sex.  
Please let me know what I can do to expedite the process of obtaining the
data. 

Dan

Question, how big a data set are you looking for? I have some extremely
large data sets for math achievement scores (old data from school district
of over 40,000 students). I probably would have to get their permission
before releasing the data (but I don't think that would be a difficulty).
Let me know.

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.

PISA item response data is publicly available at: mypisa.acer.edu.au

You'll find there 4 databases each with many many thousands of student
responses per item
