what statistic test should I use to compare the pre and post test scores between two groups?

I'll be conducting a study where I will ask both the experimental group and the control group to do a pre and post test. What statistics test should I use to measure the differences in score within and between each group? Thanks for your help!

well definitely an experiment versus an observational study or such, but how you would conduct it depends on what your factors, levels, and what you are blocking
