Educational evaluation is acquiring and analysing data to determine how each student's behaviour evolves during their academic career. Evaluation is a continual process more interested in a student's informal academic growth than their formal academic performance.

Educational evaluation consists of standardized tests that assess a child's academic ability in several subjects. The assessment shows whether the child is consistently behind in each subject, or whether specific obstacles prevent him from reaching grade level in a subject. Educational analysts usually have a master's degree or doctorate in education or psychology, and the evaluation takes three to five hours.

Examining the success of program interventions is part of training evaluation. In terms of education, they usually relate to learning, behaviour, emotional and social development or more general issues.

The importance of educational assessment:

Educational assessment is central to teaching and learning because it serves a common purpose.

• Diagnostic: Assessment is a comprehensive and continuous process. This helps the teacher to identify problems and the teacher to solve problems together with the students.

• Remedial: By remediation we mean that when problems are identified, an appropriate solution is found. The development of the student's personality and the desired change in behavior can be achieved with the help of the teacher.

• Clarify educational goals: It is also important to define the goals of going to school. The purpose of education is to change the behavior of the student. With the help of evaluation, the teacher can show how the student's behavior has changed.

• It gives guidance: A teacher can give advice only if he has enough knowledge about his students. And only after a thorough assessment, which takes into account all aspects of skills, interests, intelligence, etc., can advice be given.

• Assessment Aids: Assessment is a way for teachers to assess their students and help them determine a student's level of intelligence, ability and interest.

• Useful for improving learning and teaching: Through evaluation, the teacher can improve the student's personality and learning, and he can also know the effectiveness of his teaching. As a result, it helps improve teaching and learning.

Approaches of Evaluation on the basis of its types and functions can be classified as follows :

• Placement evaluation
• Formative evaluation
• Diagnostic evaluation
• Summative evaluation

​Strength:

Formative assessment is not graded, so it takes the anxiety out of students. Teachers can check that students understand the instructions so that he can move forward, but if not, he can take a step back due to student learning. Teachers can give instructions so that the task or activity is sufficiently understandable for the students. Formative assessment can be an exercise for students. Formative assessments can use data to help students better understand the curriculum. Very easy to apply. Teachers can evaluate themselves through a developmental assessment

Weakness:

Students may not take it as seriously as a summative assessment. This can be a time consuming process. Students need different formative assessment at different learning stages
