Pre and post-event surveys are a commonly used evaluation measure, but knowing what data to collect and how to use it can be a challenge. This webinar is an opportunity to hear from TASO’s evaluation experts about how to get the best out of pre and post-event surveys. This is a full recording of a webinar session we hosted as part of our Unlocking Effective Evaluation series, which was presented in three sections:

  • An introduction to the pre-test and post-test design and when to use it.
  • A practical example of implementing the pretest-posttest design.
  • Q&A with the audience.
