A class only counts toward a lawful purchase if it meets every statutory requirement — sheriff-verified instructor, fully in person, the right hours, the statutory curriculum, a 90% exam, and your eligibility card in hand at enrollment. The full six-point checklist is on the main finder page, along with the red flags worth walking away from.
