Ark Curriculum Plus is a not-for-profit education venture set up by the Ark Multi Academy Trust to improve subject outcomes, initially in the Ark network. We’ve now been going for over ten years, using what we learn in Ark to support over 1,000 schools nationally. Our mission is to empower teachers to give every young person, regardless of their background, the subject knowledge and skills that will allow them to succeed.

We now have subject excellence programmes in English, Maths, Science and Geography, at primary and secondary. A team of subject experts work with partner schools to empower teachers to achieve subject excellence using an ambitious curriculum combined with CPD, teaching and assessment resources.

Our programmes, including Mathematics Mastery and English Mastery, have been shown to have measurable impact in evaluations by the EEF, FFT and The Brilliant Club. The DfE is currently providing up to 80% subsidy to eligible schools to promote take-up of our Mathematics Mastery programme at primary.
