growth rate per teacher

E. Bernardo
I am using AMOS (Growth Curve Model) to compute the growth rate (SLOPE) of the teaching performance of 200 teachers from year 1 to year 4. Teaching performance is a continuous variable with values ranging between 0 and 100.  In addition to the overall SLOPE, I need also the SLOPE per teacher. Can someone suggest how to compute the SLOPE per teacher?

Thank you.  
Eins Bernardo

Eins,
 
If your linear growth curve model isn't very different than what you stated thus far, then you might consider employing the MIXED procedure. The difference in results between MIXED and AMOS should be negligible. (I have posted on this topic in the past)
 
The MIXED procedure allows you to output subject-specific predicted values. Once you obtain your subject-specific predicted values, simply subtract the predicted values for two adjacent years for each teacher and you will obtain your teacher-specific linear slopes.
