Dynamic assessment is a kind of interactive assessment used most in education. Dynamic assessment is a product of the research conducted developmental psychologist Lev Vygotsky.
Theory
Vygotsky's term Zone of Proximal Development (ZPD) relates to the gap between what the child can learn unaided and what he or she can learn with the help of an adult or a more capable peer. According to Vygotsky, it is impossible to understand a child's potential intellectual development using a one-way assessment.
Dynamic assessment is an interactive approach to psychological or psycho educational assessment that embeds intervention within the assessment procedure. Most typically, there is a pretest then an intervention and then a posttest. This allows the assessor to determine the response of the client or student to the intervention. There are a number of different dynamic assessment procedures that have a wide variety of content domains.
