test scores

with regard to the question of whether AR raises/sustains test scores, i'd like to say that i, for one, don't think that test scores were invited as part of our study. test scores, to me, are completely irrelevant to our study, as we are talking as much about readers' attitudes toward reading, writing... as we are about school success. and test scores do not assess reader attitude. and for the part where we are talking about school success, how well do test scores measure school success? how thoroughly do test scores assess subject 'intelligence', aptitude, interest, strengths, abilities...?
