The Student Experience Survey is a survey given every even year since 2002 of all degree seeking undergraduate students in the CUNY system. Results of the surveys are posted here:

Prior to the 2014 survey, a random sample of students would be invited to complete the survey using a mailed paper survey. Beginning in 2014, the survey was only able to be completed online and the survey moved from a sample survey to a population (all eligible students) survey. The 2016 survey kept this same methodology but was managed completely internally.

In May 2017, a webinar was presented that provided information about the Student Experience Survey.
