Hornchurch High School has partnered with Challenge Partners, a practitioner-led education charity accelerating school improvement, leadership development and pupil progress. Hornchurch High School takes part in a three-day, rigorous peer evaluation of teaching and learning, curriculum and outcomes, and leadership at all levels. Led by an expert lead reviewer who is Ofsted trained (but not working in an Ofsted capacity), reviews are conducted by a team of headteachers/senior leaders from schools nationally.
