Noel-Levitz surveys are generally of very high quality and the PSOL fits that description. It is the only nationally-normed satisfaction survey that focuses on the online learners that I was aware of when we first used it in 2004. Using it three years in a row gave us a good baseline for measuring overall satisfaction and also for monitoring changes in satisfaction over time. We had tried to use a survey developed internally but found the survey results to be of limited usefulness since we had no comparison data.
