Frequently Asked Questions
-
How does CLS approach Tier 1 instruction?
We believe Tier 1 instruction is the foundation of a successful MTSS system. When Tier 1 is strong, fewer students require additional support, and intervention systems function more effectively. We work with schools to strengthen core instruction by identifying and implementing research- and evidence-based practices that provide all students with consistent, rigorous learning experiences aligned to standards and instructional expectations. -
What does your Tier 1 support focus on?
Our Tier 1 work centers on elevating learning for every student through high-impact instructional practices, including teacher clarity, cognitive rigor, aligned assessment, effective feedback, and intentional use of curriculum and instructional resources. We help teams identify what is already working, refine instructional practices using evidence of impact, and ensure professional learning and instructional decisions are tightly aligned to school improvement and MTSS goals. -
Why should schools partner with CLS for Tier 1 within MTSS?
We bring deep expertise in both MTSS and high-quality instruction. Our team of experienced educators helps schools move beyond compliance-based approaches to Tier 1 and instead build coherent systems grounded in research, evidence, and local context. By anchoring professional learning, instructional practices, and collaborative structures to Tier 1 priorities, we help schools create equitable learning experiences that raise achievement for all students and strengthen every tier of support.
