Teaching Approach

Updated 7mo ago

Hillsdale High describes its approach as helping all students reach their academic and personal potential through equity, personalization, rigor, and shared decision-making. The school emphasizes a strong core curriculum, differentiated learning, collaboration among educators, and authentic learning such as project-based work, exhibitions, portfolios, and demonstrations of mastery. It also highlights smaller learning communities to build closer teacher-student relationships, support emotional well-being, and expand access to rigorous college-preparatory opportunities.
