Arguing that the problem-solving model (PSM) requires multiple data sources and flexible service delivery, this workshop will first detail the Student Neuropsychological Assessment Profile for Innovative Teaching (SNAP-FIT) project implemented in local schools. SNAP-FIT uses standardized (Tier 1) and PSM (Tier 2)RTI approaches, and for nonresponders, a comprehensive evaluation using cognitive hypothesis testing (CHT) for accurate identification and targeted interventions (Tier 3). Case examples will allow participants to gain CHT skills in developing and testing hypotheses about child strengths and needs, and learn how to brainstorm, implement, and evaluate single-subject interventions to ensure that findings have ecological and treatment validity.
