Adult Transition Program

  • Placement in La Sierra High School's Adult Transition Program (ATP) is cleared through the student's IEP.  Once cleared, students and families will be given registration instructions and La Sierra will proceed with enrollment in ATP upon the completion of the registration process.  

    Thank you for your patience and support as we transition your student to La Sierra Adult Transition Program.  We look forward to working with each of you and your families in the coming year.  Please do not hesitate to contact Assistant Principal, Renee Gates (714-447-5503/ if you have any questions.
