Which test to use?

#1
Hello

I want to analyse some test score data from a group of students that was measured at two different time points. The results of the test are continuous. And I want to see whether the results improved compared to the first reading. I have a number of other variables that I want to control for in the model (eligibility for free school meals- binary; gender - binary; school - categorical) and age (continuous). What would be the best test to see whether the scores improved over time?

Would multiple regression work?

You could perform repeated-measures analysis of variance, including age as continuous covariate and the categorical/binary predictors as between-subjects factors.
