Formative
A formative evaluation (sometimes referred to as internal) is a method for judging the worth of a program while the program activities are forming (in progress). This part of the evaluation focuses on the process.
Thus, formative evaluations are basically done on the fly. They permit the designers, learners, and instructors to monitor how well the instructional goals and objectives are being met. Its main purpose is to catch deficiencies so that the proper learning interventions can take place that allows the learners to master the required skills and knowledge.
