Guided by The Oaks Academy’s core values, the Lower School Math Interventionist provides targeted, evidence-based mathematics instruction to students identified as at-risk through universal screening and progress monitoring data. This position delivers small-group and individual intervention at Tier 2 and Tier 3 levels within The Oaks Academy’s Multi-Tiered System of Supports (MTSS) framework, addressing skill gaps in number sense, computation, and mathematical reasoning across grade levels. The Interventionist works as a member of the MTSS team, using data to drive decisions and ensuring every student receives the support needed to access grade-level mathematics. Responsibilities. Administer, score, and interpret universal screening and diagnostic assessments to identify students in need of Tier 2 or Tier 3 intervention. Conduct error analysis and skill-gap diagnostics to pinpoint specific mathematical learning needs and inform targeted instruction. Implement progress monitoring at a frequency appropriate to intervention tier and use data to make timely instructional decisions. Maintain complete and organized records of all screener data, diagnostic findings, intervention plans, and progress monitoring results. Design and deliver structured, research-validated math intervention in small groups and individually, utilizing approved curriculum and evidence-based instructional routines. Adjust pacing, grouping, and instructional focus in direct response to ongoing progress monitoring data. Partner with lead teachers to ensure alignment between intervention content and core classroom instruction. Participate actively in MTSS team meetings to review screening and progress monitoring results, contribute to placement decisions, and document team-agreed intervention plans. Collaborate with school leaders and the MTSS team to coordinate supports, manage caseloads, and facilitate smooth transitions back to core instruction when students meet established benchmarks. Skills, Knowledge and Abilities. Deep knowledge of foundational mathematics content across kindergarten through fifth grade Understanding of how students develop mathematical thinking and where common skill gaps emerge across the developmental continuum. Familiarity with MTSS frameworks, including the structures and expectations of Tier 2 and Tier 3 intervention.
