CHDA: clarity over claims.
CrescentRating's Halal Dining Assurance (CHDA) diagnostic scores an outlet's halal assurance as Muslim diners actually perceive it — an internal read for industry stakeholders, not a certification diners see.
Scored 0–10 — the same scale for every outlet.
What the grade is built from.
CHDA scores an outlet against seven weighted criteria, translating operational reality as experienced by the diner into a single 0–10 figure and one of three outcome states.
CHDA does not issue religious rulings and does not replace halal certification. It sits alongside certification, purely as an industry diagnostic — not a diner-facing product.
Each outlet lands in one of three outcome states
No follow-up questions at the table. The outlet converts the booking without friction.
The order proceeds, but only after the diner checks with staff or looks for reassurance signals first.
The booking or the order doesn't happen. Doubt resolves before the outlet gets the chance to convert it.
Most restaurants don't lose Muslim diners because they break halal rules. They lose them because they make things uncertain.
The grade in practice
Independently certified — the strongest form of verification.
No third-party certification; ownership carries the assurance by default.
No certification and no Muslim ownership; the outlet self-declares halal status.
No meat on the menu, so halal risk is assessed differently.
