Research Proposal HELP! What test to compare three groups with data before and after an intervention?

I am writing a proposal for a study

 . I have 3 groups: Group A- receiving specialized intervention technique Group B- receiving regular intervention Group C- control/receiving no intervention

  • Group A- receiving specialized intervention technique
  • Group B- receiving regular intervention
  • Group C- control/receiving no intervention

I want to compare each groupsgroup's mean on a standardized test pre and post intervention to see if the specialized intervention increased means on the standardized test. What statstest do I use?
