Arkansas Cosmetology Practice Exam

It is important to notify the department of any name changes to a cosmetology school in a timely manner to ensure proper documentation and update of records. Option B and D are incorrect as 15 days or 90 days may not provide enough time for the department to process the change before it takes effect. Option C is incorrect as 60 days is not as immediate as 30 days and could lead to delays in updating the necessary documents. Therefore, the most suitable and correct option is A, 30 days notice for a name change.
