Assessment plays a key role in schools’ improvement and teachers’ development. A teacher, who does not reflect on and introspect his/her methods and actions in the classroom/school, would tend to be repetitive in the future. He/she may teach a concept in the same way and may use the same examples and activities again and again in the class irrespective of the performance of the students. Once the teacher starts looking at himself/herself and analyses what has yielded results and what has gone wrong in the teaching-learning process and other school activities, he/she will be able to identify the areas which require further improvement.
