Taking a Test… on Someone’s Face!KaylaCohen licensed cosmetologist and owner of Kalo Beauty Simplified liked the practical parts of her cosmetology exams best. SinceKayla was learning to be a cosmetologist (someone who does hair makeup nails and other beauty treatments) half her tests were hands-on. She practiced on live models or sometimes mannequins. WhenKayla took her big state exam a proctor (supervisor at tests) watched her provide a list of services to her “client ” including mixing hair color with pretend “chemicals” (food-colored water or shaving cream) to see if she knew the correct safe mixing and application procedures.
