Glossary of Martial Arts School Business Terms
The working vocabulary of the martial arts school business, defined as this journal uses it. These are the terms that appear in tuition conversations, retention meetings and enrollment reviews across the profession — and the ones most often used loosely.
Intro
The first structured lesson a prospective student takes at a school — usually private or small-group, usually free or low-cost, and designed to end in an enrollment conversation rather than simply to sample a class. The intro is the pivot point of a school’s economics: everything spent on marketing is spent to produce intros, and everything earned depends on what share of them enroll.
Trial
A short paid or free membership — commonly two to six weeks — that lets a prospective student attend regular classes before committing to a program. A trial differs from an intro in that the student trains alongside existing members rather than being taught separately.
Show rate
The proportion of booked intros or trials that actually turn up. Schools that measure only leads and enrollments miss this: a school converting well but with a low show rate is losing students between the phone call and the front door, which is a scheduling and confirmation problem rather than a sales problem.
Enrollment conversion
The share of intros that become paying members. It is the single number that decides whether a marketing spend is affordable — the same cost per intro produces wildly different economics at a 30% conversion rate and an 80% one.
Cost per enrollment
Total marketing spend divided by the number of students it enrolled, not the number of leads it produced. Cost per lead flatters a channel that generates enquiries who never enroll; cost per enrollment is the figure that can be compared against a student’s value.
Average ticket
Average monthly revenue per active student, across all programs and tiers. It is the cleanest single measure of a school’s pricing position, and the number most owners underestimate because they think in terms of their base tuition rather than what students actually pay once upgrades and additional programs are counted.
Student lifetime value
Average ticket multiplied by the average number of months a student stays, plus non-tuition revenue such as testing, gear and events. It is the ceiling on what a school can rationally spend to acquire a student.
Attrition
The rate at which active students leave, usually expressed monthly. In this profession the difference between a school that grows and one that stalls is frequently one or two percentage points of monthly attrition, because the effect compounds: a school losing 5% of its students each month replaces its entire roster in under two years.
Back-door attrition
Students leaving quietly while the school’s attention is on new enrollments. It is called the back door because nobody announces it — attendance thins, a payment fails, and the student is gone without a cancellation conversation. Schools with a front-door problem know they have one; schools with a back-door problem often do not.
Renewal chain
The sequence of program renewals a student passes through over a martial arts career — beginner program to intermediate, intermediate to black belt program, black belt program to instructor or masters track. Each renewal is a decision point at which the student either re-commits for a longer horizon or becomes a monthly member at risk of drifting away.
Black Belt Club
A mid-level program tier, typically committing a student to train through to black belt in exchange for additional classes, curriculum or privileges at a higher monthly rate. It is the most common structural upgrade in the profession and the mechanism through which most schools raise average ticket without raising base tuition.
Leadership program
A senior program tier for students training toward instructor qualification, usually adding teaching practice, additional class time and a longer commitment. It serves two purposes at once: it retains a school’s most advanced students and it produces the instructor pipeline the school needs to grow.
Paid in full
A membership paid as a lump sum for the whole term rather than monthly, normally at a discount. It improves cash position immediately and removes billing risk, at the cost of some total revenue and of the monthly touchpoint that surfaces a wavering student.
EFT
Electronic funds transfer — the recurring automatic payment, usually from a bank account or card, on which most martial arts school membership billing runs. A school’s EFT base is its predictable monthly revenue, and the health of that base matters more than any single month’s enrollment figure.
300 at 300
Shorthand for a school with 300 active students at an average ticket of $300 a month — $90,000 a month, or roughly $1.08 million a year in tuition. It is used in this journal as a reference point rather than a target, because it isolates the two variables that actually determine a school’s size: how many students it keeps, and what each one pays.
Active count
The number of students currently paying and attending, as distinct from the number on the database. The gap between the two is where most owners overestimate the size of their school; a student who has not attended in eight weeks is an attrition event that has not yet been recorded.
Program tier
A defined level of membership with its own curriculum, class access, term and price. Tiering is what allows a school to serve a casual student and a career student in the same building without pricing either one wrongly.
Upgrade
Moving a student from a lower program tier to a higher one, typically at a renewal point. Upgrades are the principal lever on average ticket in an established school, because they raise revenue from students who have already demonstrated they will stay.
Front desk conversion
The share of inbound telephone and web enquiries that are converted into a booked intro. It is the least-measured number in most schools and frequently the cheapest one to improve, because the enquiries have already been paid for.
Mat capacity
The number of students a school can physically and safely teach given its floor space, class schedule and instructor count. It sets the point at which growth requires more class times, more instructors or more space rather than more marketing.
Definitions here describe general practice across the profession as Martial Arts Professional has documented it since 1996. Where a figure appears it is illustrative arithmetic, not an industry average — this profession has no census, and an undated industry average is worth less than one school’s audited numbers.
