Math - Tier 3

Tier 3 targets the students with the most complex needs. At Tier 3 identified needs have not been adequately met through access to available basic tools and strategies Tier 1 or additional strategies and trials with available equipment Tier 2. Students may now require a specialized evaluation to determine individual needs. They may also require additional follow-up and technical interventions to support recommended technology. At Tier 3, the teacher and other specialists work collaboratively with the AT Specialist to complete an evaluation of needs and identify appropriate technology and services to support student needs. They may develop an Implementation Plan to support recommended technology over time. Using the roles and responsibilities guidelines below, the evaluation is conducted and the IEP Team decides what technology will be provided and how the technology will be implemented. In some cases, long term trials may be required along with ongoing assessment.
