About the Role

The Director of Math K–12 is an academic leader responsible for the vision, coherence, and quality of Ascend's mathematics curriculum, instruction, assessment, and professional learning across grades K–12. This role ensures that all students experience a rigorous, coherent, and joyful mathematics program that builds deep conceptual understanding, procedural fluency, and problem‑solving skills across grade levels.

The Director of Math K–12 oversees the selection, design, adaptation, and implementation of math curricula and assessments; leads math‑focused professional development for school leaders and teachers; and uses data to drive continuous improvement. The Director of Math K–12 works closely with Teaching & Learning, Schools, and School Leadership teams to ensure high‑fidelity implementation of math curriculum and instructional practices across all Ascend schools.

This role is intentionally scoped more narrowly than the Associate Director of STEM K–12, with exclusive focus on mathematics rather than cross‑disciplinary STEM content, while expanding the grade‑band responsibility to K–12.

Data & Continuous Improvement

• Analyze instructional and assessment data to inform curriculum revisions, professional development priorities, and instructional supports.
• Partner with data and analytics teams to refine math assessment systems and reporting structures.
• Monitor implementation fidelity and student outcomes to drive ongoing improvement.

Cross‑Functional Collaboration

• Work closely with Teaching & Learning, Schools, and School Leadership teams to ensure alignment between curriculum, instruction, and school‑level execution.
• Partner with academic operations and platform teams to ensure math curriculum and assessments are accurately configured in digital systems.
• Collaborate with other content leaders to maintain coherence across disciplines while preserving math‑specific rigor and focus.
