Like a print teacher’s kit, they are sold by grade level. E.g. if you are a counselor teaching Lions Quest 6-8, then you would need one license each for grade 6, 7, and 8.
The one exception is the high school program, Skills for Action, which is sold as one license for all four grades 9-12. (Just as the print program was sold as one Teacher’s Kit for grades 9-12). E.g. if you’re a high school counselor teaching all grades, you only need to purchase one Skills for Action license for $199.
