Given that there is a continual need for school counselors to describe and account for what they do, it follows that an instrument that can be used to collect relevant process data is warranted. The importance of collecting process data describing school counselor practice is widely supported as a component of accountability. However, the lack of practically significant and valid instruments may hamper this practice. The purpose of this study was to examine initial validity, and reliability data on the School Counselor Activity Rating Scale, an instrument that school counselors could use to gather process data. The School Counselor Activity Rating Scale was designed to measure how school counselors actually spend their time versus how they would prefer to spend their time in job-related activities. Its development, initial validity and reliability results, and potential applications are presented in this article.
