Progressive Intervention can either referred to as a Standard Protocol Approach or as a Problem Solving Model.[vi] Both models incorporate problem solving to identify the academic problem the student is having. The main difference among these approaches is that the former uses a systematic, universal screening procedure during Tier 1 to determine which students are having difficulties meeting age or grade level benchmarks for a specific skill. Typically, several program fitness, content diagnostic skills, and student willingness assessments or interviews are incorporated into the student admissions process for online programs as a component of their PI model. Students who are not meeting expected levels of performance at point of admission to the online program can be admitted to the program under Tiers II or III in an effort to aggressively support their program success. In the problem solving model approach, the mentor or program coordinator typically evaluates the student’s performance using pre-identified Key Performance Indicators. Using information collected from the Learning Management System (LMS), observations, interviews, etc., the coordinator or team determines the intervention tier placement the student might need to address the learning or performance gap.
