    Access, Advisment and Seminar - what are they, what is the difference between them, and how are they graded?

    Access - Meets every Thursday. The purpose of Access is to offer students an opportunity to get extra academic support. During Access, students can travel to different classrooms to meet with teachers and get additional help they may need in a specific class. This class is a Pass (P) or Fail (F) class based on 60% attendance.

    Advisement - Meets every Tuesday. Students receive a Pass (P) or Fail (F) grade for Advisement based on completion of work and 60% attendance.

    Material covered in Advisement is:


    • Executive functioning skills

    • Navigating high school

    Seminar - Meets every Tuesday and Thursday. Seminar is a cornerstone of ThunderRidge where students and staff try to establish positive relationships and a sense of community over the 4 year high school journey. Many of our traditions are based in this class. Students stay with the same teacher all the way through high school, ending with their Seminar teacher announcing their names at the graduation ceremony. This class is a Satisfactory (S) or Unsatisfactory (U) grade based on 60% attendance.

    Special Education records which have been collected by Douglas County School District related to the identification, evaluation, educational placement, or the provision of special education in the district, must be maintained under state and federal laws for the period of five (5) years after special education services have ended for the student. Special education services end when the student is no longer eligible for services, graduates, or completes his/her educational program at age 21, or moves from the district. This notification is to inform parents/guardians and former students of Douglas County School District's intent to destroy the special education records of students who exited special education services as of June 30, 2016. These records will be destroyed in accordance with state law unless the parent/guardian or eligible (adult) student notifies the school district otherwise. After five years, the records are no longer useful to the district, but may be useful to the parent/guardian or former student in applying for social security benefits, rehabilitation services, college entrance, etc. The parent/guardian or eligible (adult) student may request a copy of the records by requesting the records at this link ( Douglas County School District Transcripts and Records Requests ).
