Identifying appropriate methods for data collection — and subsequently developing them — is an important part of performance evaluation. This effective practice will help programs decide when to use survey questions with scaled response choices and understand how to develop clear questions for these types of evaluations. Three commonly used instruments will be addressed — agreement, evaluation, and frequency scales. When used appropriately, scaled questions can yield high-quality data in a format that is relatively easy to summarize and report. Project STAR shared this effective practice in June 2007.
