This work represents a formative evaluation of the effect of Deep Freeze on the labs in the Networking, Security, and Systems Administration department. This department maintains 4 labs for student use and has implemented Deep Freeze, a software package intended to maintain a standard set of configurations on each computer. In order to provide a proper focus to the evaluation, the process consisted of identifying specific evaluation questions, first through a diverging process, including the input of key stake holders, followed by a converging process. The data was collected using both a survey instrument and interviews, providing both quantitative and qualitative data. This process resulted in information that Deep Freeze does indeed save time for the lab technicians, both in the duration of imaging and in the number of times the labs need to be imaged. Additionally the labs are kept more consistent, the practicals run smoother, and the students like the program. However, students do need to be constantly saving their work off the computer in order to prevent data loss due to Deep Freeze.
