Association of School and College Leaders

What Association of School and College Leaders does

The Association of School and College Leaders (ASCL) is the principal UK trade union and professional association for leaders of schools, colleges, and multi-academy trusts, serving over 25,000 members across England, Wales, Northern Ireland, and Scotland. Founded as the Association of Headmistresses in 1874 and renamed to its current form in January 2006 after progressive membership broadening, ASCL combines statutory union representation (collective bargaining, employment and legal advice, pay and conditions support) with a professional development arm delivered via its wholly-owned subsidiary, ASCL Professional Development Ltd. The subsidiary organises CPD programmes, conferences, leadership recruitment (Leadership Appointment Service), consultancy (Trust Reviews, Data Management, ICFP, Coaching), and major events including the ASCL Annual Conference and the co-branded Tes SEND Leadership Summit.

ASCL's core technology stack is deliberately limited: it operates a website platform for membership enrolment, event booking, and resource distribution, holds Cyber Essentials certification across both ASCL and ASCL PD entities, and distributes content via Leader Magazine, podcasts, weekly newsletters, and a blog. Premier Partners (Browne Jacobson, Cooper Parry, InVentry, Quilter, Unifrog, Barker Associates, BlueSky) and Preferred Suppliers (Education Mutual, Academy21) extend the service set, while ICP and ESHA memberships anchor international reach.

Revenue is subscription-led and disclosed at £8,653,382 for the period ending 31 December 2025, of which £7,486,334 (~86.5%) derives from membership fees, with the balance from CPD/conference income, leadership recruitment fees, and bespoke consultancy. Pricing is tiered by role and event format, with webinar packages at £50+VAT and £500+VAT, member-discounted conference rates, and variable cancellation fees. Total expenditure of £9,131,722 produced a modest operating deficit, indicating the organisation is reinvesting at or near the level of income to sustain services. ASCL is headquartered in Leicester, is governed by an elected Council of approximately 60 members, and is led by General Secretary Pepe Di'Iasio.

Direct peers

• National Association of Head Teachers (NAHT): NAHT is the other major UK trade union and professional association specifically for head teachers, deputies, and assistant head teachers. It directly competes with ASCL for the same leadership persona, runs parallel CPD, advice, and policy advocacy services, and contests members in the same primary, secondary, and MAT leadership segments.
• National Education Union (NEU): NEU is the UK's largest education union, formed by the merger of the NUT and ATL. It represents teachers and school leaders, engages in collective bargaining on pay and conditions, and provides professional learning and policy advocacy — making it a broad peer competing for member mindshare across the UK education workforce.
• NASUWT: NASUWT is a major UK teachers' union representing teachers, head teachers, and school leaders across primary, secondary, and post-16 phases. It competes directly with ASCL for leadership members, offers employment advice and CPD, and engages in similar collective bargaining and policy advocacy activities.
• Chartered College of Teaching: The Chartered College of Teaching is the chartered professional body for the teaching profession in the UK, offering membership, professional development, research, and a chartered status pathway. It overlaps with ASCL's CPD and professional standards offering and targets similar educators and school leaders seeking formal professional recognition.
• Headmasters' and Headmistresses' Conference (HMC): HMC is a professional association of heads of leading independent schools in the UK and Ireland. It mirrors ASCL's role for school head leaders but in the independent sector, providing conferences, CPD, advocacy, and recruitment support — overlapping directly with ASCL's leadership support, events, and consultancy services for the independent segment.
• Society for Education and Training (SET): SET is the professional membership body for educators working in the post-16 and further education sector, offering CPD, qualifications, and professional standards support. It directly parallels ASCL's college leader membership, CPD programmes, and policy work for post-16 leadership.

Broad incumbents

• Independent Schools Council (ISC): ISC is the umbrella body representing the UK's independent schools associations. While broader than ASCL's leadership-focused proposition, it engages in policy advocacy, sector representation, and member services that overlap with ASCL's independent sector leader support and policy influencing activities.

Emerging players

• National Governance Association (NGA): NGA is the membership organisation for school governors, trustees, and governance professionals in England. It overlaps with ASCL in the trust governance and academy leadership support space (training, advice, policy), targeting an adjacent but related leadership persona within schools and MATs.
• British Educational Leadership, Management & Administration Society (BELMAS): BELMAS is a professional learned society for educational leaders, managers, and administrators across the UK. It overlaps with ASCL on research, networking, and professional development for school and college leaders, though with a more academic and scholarly orientation than ASCL's trade union-led approach.
• Headteachers' Roundtable: Headteachers' Roundtable is an informal network and advocacy group of serving head teachers that engages in education policy debate and influence. It intersects with ASCL's policy influencing and thought leadership activities, particularly around curriculum, assessment, and accountability reform.
