This document discusses an approach to addressing "swiss cheese" skill gaps in below grade level students entering 7th grade. It involves identifying core 7th grade target skills and then determining the specific skill gaps for each student related to those targets. Teachers focus on filling in each gap by working up from the student's current level to the 7th grade target, one target at a time. This results in a unique multi-grade learning plan for each student. A study found this approach helped below grade level students achieve learning growth 1.8 times the national average, equivalent to an extra 8 months of learning.
