Which statistical analysis needs to be run ? ANOVA/Paired T-Tests

#1
So i trying to figure out what analysis i need to use,but im a tad stuck.

Im doing a pre and post test design.

So a primary school with a programme , measured by the questionnaire before and after . Then there is a control group primary school without a programme , measured by a questionnaire before and after.

Then a high school with a programme, measured by the questionnaire before and after . Then there is a control high school without a programme, measured by a questionnaire before and after.

i have 4 groups and just want to look at the effect of 'time' impact of the programme on primary and high school students.

what do i use ???
any help would be appreciated.
