The ELA foundational skills rubric contains only two gateways: Alignment to Standards and Research-Based Practices for Foundational Skills Instruction (Gateway 1) and Implementation, Support Materials & Assessment (Gateway 2). The structural pieces that we normally review as a part of Gateway 3 (e.g. differentiation) in our comprehensive reviews are critical to the success of a program, and are, therefore, interspersed and combined with other indicators in Gateway 2.
