High School Diploma

The High School Diploma program is offered to adults wanting to complete their high school credits to earn a diploma.  Students will use our curriculum to progress through the coursework at their own pace. 


The teacher is available during class hours to assist students, monitor progress, and supervise exams. It is required that students maintain contact with the teacher either by attending class sessions, or attending remote/online meetings as assigned by the teacher.  


A distance learning program is also available to students that meet the minimum requirements.  All work is completed using an online program, and the student will check-in with the teacher by email or phone calls.  The final exam is to be completed in class under the supervision of the teacher.



Enrollment and assessment tests will be completed at the office:

  • Snowline Adult School/NTS West Campus 9258 Malpaso Rd. Phelan, CA 92371

New Student Orientation will be in the classroom, by appointment:
