Good educational outcomes are a residue of having qualified and experienced teachers. The quality of a good teacher is weighed through the teacher’s evaluation. A teacher’s evaluation puts out their performance and conduct in context and compares them against a set of certain standards. Evaluating teachers has proved a daunting task yet crucial because it informs future decisions. The evaluation must set clear and rigorous expectations to be successful and effective. Teachers’ evaluation is also made fair by using objective data to measure the performance against some standards. Finally, giving evaluation feedback enables the teachers to reinforce their strong points and improve their shortcomings. Other benefits include improving teacher quality, accountability, better teacher-student collaboration and encouraging professional development. At Sackhumvit we find reviewing encourages observation, perception and general awareness both during and after experiences. By reviewing activities we show that we care about what people experience, that we value what they have to say, and that we are interested in the progress of each individual's learning and development.
