At CISA, we have designed a regime of interactive assessment and instruction that is skill-based and personalized. Henceforth, using a data-driven approach, each assessment will provide our teachers with information about the child’s growth trajectory on a set of foundational skills, information designed to help teachers evaluate their students’ progress, reflect on past instruction, and strategize the next phase of instruction. By individually assessing each child and using specially designed statistical software to track each child’s progress, the teacher gains a clear understanding of what the key skills are, what each child knows, and what each child needs to know to advance to the next level.
