What Ark Curriculum Plus does

Ark Curriculum Plus (legal name Ark Curriculum Plus, DBA Ark UK Programmes; registered charity 1137932; company 05932797) is a UK-based, London-headquartered education organisation founded in 2013 as part of the Ark multi-academy trust network. It develops and licenses subject excellence programmes in English, Mathematics, Science, and Geography across primary and secondary levels, alongside a structured AC+ 5-Step Improvement Process (Plan, Train, Teach, Embed, Sustain) for school transformation. Its customers are state schools and Multi-Academy Trusts (MATs) across the United Kingdom, with named relationships including large MATs such as TKAT, Leigh Academies Trust, St Joseph Catholic MAT, Three Saints Academy Trust, and Summit Learning Trust, plus a 100-school English curriculum efficacy trial with the Education Endowment Foundation (EEF).

The core technology and product surface comprises curriculum-integrated planning tools, lesson resources, standardised assessments, and CPD content, delivered through the MyMastery digital learning platform (provided in partnership with Accipio Digital Ltd). The product portfolio currently includes seven programmes: English Mastery (Primary and Secondary), Mathematics Mastery (Primary and Secondary), Geography Mastery (Secondary), Science Mastery (Secondary), and Science, History and Geography Mastery (Primary). Each subscribing school is assigned a dedicated subject expert who supports a multi-year improvement journey, with on-demand video CPD, diagnostic data, benchmarked assessments, and access to Subject Teaching Networks for ongoing collaboration.

The business model is B2B subscription-based, with schools and MATs paying recurring fees for multi-year programme access; pricing is consultative and not publicly disclosed. The go-to-market combines a sales-led direct motion ('Book a call' CTAs, dedicated subject experts) with a product-led free programme preview that provides sample lessons, activities, assessments, and CPD to drive adoption. Marketing channels include an extensive blog, webinars, an annual conference, regional showcases, case studies (50+ across primary, secondary, and MAT categories), and organic social on LinkedIn, X, Facebook, and YouTube. Independent validation is provided by EEF, FFT (Fischer Family Trust), and The Brilliant Club, supplemented by strategic partnerships with Shakespeare's Globe, Oxford University Press, Peters, and Ambition School Leadership.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• White Rose Maths: UK maths curriculum and mastery programme provider serving primary and secondary schools with lesson resources, assessment and teacher training. Most directly comparable peer given the shared mastery-maths approach and UK K–12 focus.
• Twinkl: UK-based subscription educational resources publisher selling lesson plans, assessments and CPD-style materials to primary and secondary schools. Directly comparable as a digital curriculum and teaching-resource subscription model targeting the same UK school buyer.
• Hamilton Trust: UK charity providing free and subscription lesson plans, planning resources and home-learning materials for primary schools. Comparable as a UK primary-focused curriculum resource provider with a similar subject-coverage footprint in English, maths and science.

Others

• NCETM (National Centre for Excellence in the Teaching of Mathematics): UK government-backed body coordinating Maths Hubs and mastery professional development. Comparable because it operates in the same maths mastery and teacher CPD space as Mathematics Mastery Primary, but is publicly funded rather than a subscription service.
• BBC Bitesize: BBC's free online study support platform covering primary and secondary subjects including English, maths, science and geography. Comparable as a curriculum-aligned learning resource for UK schools, though free and broadly available rather than a subscription programme.

Broad incumbents

• Pearson Education: Large global education publisher with significant UK K–12 curriculum, assessment and CPD offerings. Comparable as a broad incumbent operating in the same K–12 curriculum and assessment space, though as part of a much wider portfolio rather than a mastery-specialist.
• Oxford University Press (Education): Major UK K–12 curriculum publisher with primary and secondary resources and CPD. Already a strategic partner to Ark Curriculum Plus, but also a broader incumbent serving the same UK schools with overlapping subject coverage.
• Hodder Education: UK educational publisher providing textbooks, digital resources and teacher support across secondary subjects including English, Science and Geography. Comparable as a UK curriculum publisher targeting the same secondary school buyers.
• Cambridge University Press (Education): International educational publisher with UK K–12 curriculum resources, assessments and teacher materials. Comparable as a broad incumbent with overlapping subject coverage and similar school-buyer relationships in the UK.

Emerging players

• Carnegie Learning: US-based maths curriculum and adaptive learning provider built around a mastery / cognitive-science approach. Comparable as a subject-specialist maths mastery provider with K–12 focus, though primarily operating in the US rather than the UK market.
