William, you said you cannot link students from time 1 to time 2.  I gather this means that there are students (possibly a substantial number) who have data for both time points, but you lack the unique student IDs required to link the two data points.  Is that correct?  If so, I imagine there are also some students who have data for only one year.

Thanks for clarifying.

I need to look at change over time  (year 1 year 2) in Math scores
measured at the student level with students nested within Schools.

I have the same 13 schools at both time points
However I cannot link students from time one to time two.
The number of students within a school varies both within a year and across
schools
and within a school across years.


Is there a way to model the effect of time
 in SPSS Mixed so that I can capitalize on the fact that schools are
repeatedly measured.?

Thanks in advance
