At AIS I have introduced the Outstanding Teacher Profile. This is a simple proficiency scale for teachers that allows us to set expectations and aspirations regarding the characteristics and actions of an outstanding teacher at our school. It also facilitates the collection of data that we use to determine our AIP priorities for Teaching and Learning as well as allowing us to plan for deliberately differentiated professional development for our teachers. In addition, it allows collection of data, through teacher self evaluation, learning walks and focused observations, that can be used to determine the impact of PD and/or other interventions for each/any aspect of the profile. Our observational coaching model and APR goal setting also stems from the profile and is an excellent way to facilitate and monitor improvement in practice.
