Membership categories
Membership categories, built around how members differ.
Grades, classes and types of membership for associations and professional bodies. Keep a category when it changes what a member has earned, the rights they hold or who the member is. Turn the rest into discounts.

Every categoryearns its place
01/ types of membership
Categories sort members by what they’ve earned.
A membership category is a class of member with its own criteria, rights or fee. Most structures mix four kinds: grades a member earns, classes with different governance rights, concessions for circumstances, and organisational membership.
Only the first three need to be categories. Grades carry the weight in a professional body. On the engineering register, just under 80% of registrants hold Chartered Engineer as their highest title (Engineering Council, 2024).
Concessions are where lists grow. A retired or overseas rate changes the price, not the status. Pricing each one is a job for membership pricing.
Engineering register by highest title, end of 2024
- Chartered Engineer (CEng)167,713
- Incorporated Engineer (IEng)23,104
- Engineering Technician (EngTech)23,033
- ICT Technician (ICTTech)821
02/ membership grades
Designatory grades: the ladder members climb.
A grade structure is a ladder. Each rung has entry criteria and, often, letters after the name. The Engineering Council ranks Chartered Engineer highest, then Incorporated Engineer, then the technician titles; 3.6% of registrants hold more than one (2024 summary).
Criteria do the work, not names. In the Royal College of Anaesthetists’ proposals, post-nominals depend on passing the FRCA examinations, and Fellowship comes by examination or nomination (RCoA).
Adding a chartered grade is a bigger step. The Privy Council Office expects internal and external consultation before granting an individual Chartered designation.
Student
Studying towards the qualification. Entry rung, usually no vote.
EntryAffiliate
Interested, not qualified. Beside the ladder, not on it.
Non-votingAssociate
Qualified, early in practice. First letters after the name.
GradeMember
Fully qualified and experienced. The core voting grade.
VotingFellow
Senior standing, by assessment or nomination.
DistinctionChartered
A designation awarded under a Royal Charter, on top of a grade.
CharterThe ladder is a common pattern, not a rule. Your criteria and names come from your own charter, articles or regulations.
03/ membership structure
A grade ladder needs joiners at the bottom.
Grades keep members: retention on the engineering register has held at 94–96% for seven years. But a ladder only grows if enough people step on.
In 2024, 9,368 people joined the register and more left, a net loss of 3,531. The average registrant joins at 34 and leaves at 59 (Engineering Council). The bottom rungs are where that gap closes.
So design the entry grades as carefully as the top ones. A student or associate grade that is easy to understand and easy to step up from is the recruitment plan. Joiner numbers are covered in membership growth consultancy.

04/ membership classes
Three ways to structure your categories.
There are three common shapes. One category plus discounts keeps a single class and prices circumstances. Graded categories give each grade its own criteria and fee. Benefit tiers sell more access for more money.
The Royal College of Anaesthetists put three proposed models to members after more than 65% of its 2025 survey respondents backed simplifying. One model is a single fee for all with discounts; the others give each category its own fee (RCoA). It asked members to choose a model before it set fees.
That order is right. Settle the structure, then price it on membership pricing. What each tier includes is on membership fees and benefits.
05/ retired, student and overseas members
Retired, student, overseas: category or discount?
Usually a discount. In the RCoA’s single-fee model, trainees, retired, lower-income overseas and student members pay the one fee less a set percentage (RCoA, proposals subject to change).
Pensions UK went further. It planned to remove its International Member category and move those members to whichever of its five classes fits, because online services made geography less of a barrier (Pensions UK, Oct 2025).
Concessions are common for students, rarer elsewhere. In a peer-reviewed survey of 182 international societies, 83% offered student concessions, 43% discounted for the Global South and 26% for postdocs. The rates themselves belong on membership pricing.

06/ voting rights by category
Voting rights by category, written down.
In a company without shares, each member has one vote unless the articles say otherwise (Companies Act 2006, s.284). The articles are where you give or withhold a vote by category.
Write it plainly. The Charity Commission’s RS7 found confusion over which members can vote was a common cause of trouble in membership charities, and asked trustees to set out the rights of each type of member. 44% of the charities it surveyed had voting members (2004 report, dated).
The RCoA ties voting in Council elections to medical grade and a licence to practise (RCoA). Rights follow criteria, not fees.

Drawn from the Charity Commission’s RS7 (March 2004, dated), which separates voting members from supporters, friends and affiliates with no governance role. Your articles decide who sits where.
07/ changing categories
Changing categories: who has to agree.
Where a category is written down decides who signs off the change. Find that first.
Companies. A class’s rights can be varied only as the articles allow or, failing that, with three-quarters of that class in writing or a special resolution at a class meeting (s.631). CIOs. Changing how members are admitted needs no Commission authority, but a members’ resolution needs 75% of those voting at a general meeting (CC36).
Chartered bodies. Bye-law changes need Privy Council approval, through an informal and a formal stage of about 4–8 weeks each. Engineering institutions consult the Engineering Council first (Privy Council Office). More than 1,000 Charters have been granted (PCO FAQs).
Pensions UK shows the sequence: meet affected members, consult formally, decide, then phase. Of 49 affected members it met, 36 were positive or broadly positive (Pensions UK). Fee changes from a review are on subscriptions review. Not legal advice.
Can you change categories without a members’ vote?
01Are your categories set out only in regulations or policy, not in your articles, constitution or bye-laws?
02Will every class keep the rights it has now: votes, offices, letters after the name?
03Will everyone who votes today still vote afterwards?
Answer the 3 questions to see where you stand.
From Companies Act 2006 s.631, Charity Commission CC36 and Privy Council Office guidance. A screen, not legal advice.

08/ simplify membership categories
Simplify your categories in five minutes.
Tick every category you run. Each one is sorted by what it actually changes, and the ladder that is left is your simpler structure.
The test is ours, and it is plain: a category earns its place if it changes what a member must have achieved, the rights they hold, or whether the member is a person or an organisation. Everything else is a price, and belongs in the fee table as a discount.
Organisational membership is a separate scheme; see corporate membership. To test a new structure on members before you commit, see price and proposition testing.

4 categories could go
Most of your list is price, not status. Members see a long menu; you run it.
Merging a class with its own rights is a change to your articles, rules or bye-laws. Check who must agree first.
Our rule, not a benchmark: a category earns its place if it changes what a member must have achieved, the rights they hold, or whether the member is a person or an organisation. One that changes only the price is a discount. Nothing you tick leaves your browser.
09/ membership categories review
Reviewing categories: scope, brief and budget.
Real briefs put categories inside a wider review. ARMA’s governance review tender lists “membership criteria, categories, rights and admission processes” beside the articles and the board, with a £10,000 budget excluding VAT (ARMA).
Smaller bodies fold it into a membership model review. CLOA’s brief covers benefits, pricing structure and benchmarking for up to £3,200 (CLOA); ASCEL asked for recommendations on structure, membership make-up and subscriptions (ASCEL, 2018).
