The 321SOS assessment tool has been developed by BLaST Intermediate Unit 17 as a way to standardize and simplify teacher and staff evaluations. The custom program allows observers to perform assessments and job evaluations with most internet-capable mobile devices. The easy-to-use interface can be mastered by the most inexperienced users. Troubleshooting and program updates will be handled by the BLaST Intermediate Unit 17 technology staff as part of the basic service agreement.
