[Strategy] Compacting [Definition] Compacting is the process of adjusting instruction to account for prior student mastery of learning objectives. Compacting involves a three-step process: (assess the student to determine his/her level of knowledge on the material to be studied and determine what he/she still needs to master; create plans for what the student needs to know, and excuse the student from studying what he/she already knows; and create plans for freed-up time to be spent in enriched or accelerated study. [Example] A student who can decode words with short vowel sounds would not participate in a direct instruction lesson for that skill, but might be provided with small group or individualized instruction on a new phonics skill.
