Is it enough to just assess grades four and eight...

Reply 1:

Evaluations often use a subset of grades to represent the effects of an intervention on an entire project. In fact, many states test in only a few key grades and use the results to represent the progress of the entire system. In an ideal world, one would want to collect data for all grades involved in an LSC project. However, time and money issues can prevent one from doing the ideal. Using only grades 4 and 8 may be the best that can be done. However, one would want to be able to explain why factors other than LSC were not the possible reasons for changes in scores. Determining if it is reasonable to use the scores from just these two grade levels would also depend on what grade levels are a part of the project and how teachers are brought into it (e.g., one grade level at a time or randomly across all grade levels).
