The Teacher Success is designed as both a diagnostic and prescriptive professional development tool for k-12 teachers. The software streamlines the process of teacher and leader observations, allowing evaluators to input data online easily via laptop or mobile devices and to generate insightful reports and graphs. It is highly customizable, supporting local evaluation frameworks and reports. Once trends or target areas for improvement have been identified, the Teacher Success automatically suggests online professional development from a library of thousands of videos, tutorials and online modules. The PD library enables teachers and school leaders to browse, search and share professional development content from renowned authors such as Robert Marzano, Rick Stiggins, John Saphier and many others. This app enables evaluators to perform walkthroughs, observations and evaluations without an active Internet connection. Observation data can then be synchronized with online accounts when the evaluator is back online.
