Participation in one or both programs depends on the number of students participating and drinking milk. If your school meets the minimum number of students participating in each program, you can absolutely run both programs! If your school does not meet the minimum number of students for each program, you will be asked to choose either the Elementary School Milk Program or the High School Milk Program. All students in the school (kindergarten through Grade 12) can participate in the program, regardless of which you choose. We recommend the High School Milk Program for small kindergarten through Grade 12 schools, as the milk rewards are more age appropriate for older students.
