BJJ Gym Culture & Safety Navigator Grappler Toolkit

Subjective culture checklist and illustrative budgets. Scores do not diagnose infection or certify a safe training space.

Academy Dimensions & Observed Red Flags
Mat Sanitation & Disinfection Frequency Rarely Mopped (0/10)
0 = Irregular cleaning; 10 = Consistent, documented cleaning. Use the actual product and mat labels.
Ego & Rank Hierarchical Fragility Severe Rank Resentment (9/10)
0 = Welcoming tap-learning; 10 = Higher belts blow up if tapped by lower belts.
Promotion Basis (Merit vs Clique Favoritism) Favoritism & Cookouts (2/10)
0 = Loyalty tests & BBQ attendance; 10 = Transparent technical criteria.
Extremist / Hostile Social Dynamics High Pressure / Polarized (8/10)
0 = Neutral respectful training; 10 = Ostracizes non-conforming worldviews.

Questions to Discuss

Separate checklist scores from health and safety evidence

What can a high culture score tell you—and what must still be checked?

Use the sliders to organize observations about cleaning, instruction and consent. The number is an authored weighted checklist, not an infection probability. Compare the score with actual cleaning records, partner conduct and professional advice.

Mat prices, occupancy and chemical outputs are inherited assumptions. No product labels, laboratory tests, room inspection or current vendor prices are supplied. Do not use the chemical examples to mix or apply a disinfectant.

Try a worked example

With all four sliders at 5 and no flags, the score is 50/100: 17.5 cleaning + 12.5 reverse ego + 10 promotion + 10 reverse hostility. Turning on the skin flag subtracts 18 to give 32/100. That penalty is a design choice, not an 18% infection estimate. A 144 sq ft rollout budget gives round(144 × 4.8 + 80) = $771, with a $964 upper figure; neither is a vendor quote.

What the score actually counts

Cleaning, reverse ego, promotion and reverse hostility have weights 35, 25, 20 and 20. Flags subtract 18, 15, 6 and 6 points; the result is rounded and clamped to 0–100. Thresholds at 45 and 70 change the discussion prompts. None of those weights or thresholds are validated medical measures.

Use current guidance rather than invented prescriptions

CDC advises prompt showering after exercise, avoiding shared personal items, laundering clothing after use according to its label and getting medical attention for suspected infection. These steps do not make an uninspected gym safe. CDC: athletes and MRSA prevention

CDC facility guidance calls for cleaning shared equipment, following equipment instructions and disinfectant labels, including application, contact time, surface compatibility and rinsing. Product names such as quat or peroxide are not sufficient to select a dilution. Never put cleaning chemicals on skin or wounds. CDC: athletic facilities and MRSA prevention
