High school guide

Grade level classifications

Grade level classification is based on the number of credits successfully completed at the end of the year or summer school.

  • 10th grade - 6 credits
  • 11th grade - 12 credits
  • 12th grade - 18 credits

Students must conform to the classification to participate in class activities or events.

High school scheduling

Semesters and grading periods

For all high school campuses, the school year is divided into two semesters with two grading periods in each semester.

Block scheduling

High schools use A/B block scheduling. This block schedule consists of an eight period schedule with four 90-minute class periods on "A" days and four 90-minute class periods on "B" days. Students can earn a maximum of 8 full credits (16 semester credits) on this schedule.

“A” days will be on Monday and Wednesday. “B” days will be on Tuesday and Thursday. Friday schedules will alternate between “A” and “B” days – see the A/B block schedule for more information.

A/B calendar

You can find the A-day/B-day block schedule for the current school year in the printable resources section of the school year calendar page.

Double-blocked classes

Certain courses associated with special programs (fine arts, athletics, CTE internships or career preparation programs, etc.) receive special attention in the scheduling process. For example, students participating in football or basketball will probably be scheduled into an athletic period during the school day every day all year long. We often describe these courses as double-blocked.

If you plan to be involved in one or more of these special programs during high school, you may need to consider additional credit opportunities. Your high school counselor is the best person to consult with about your schedule and four year plan.

Dropping or adding courses

Students must take at least six credit-bearing courses at all times. Three of these courses have to be academic core courses selected from:

  • English
  • mathematics
  • science
  • social studies
  • computer science
  • other languages
  • other AP courses
  • Accounting II
  • Future Teacher Studies (BESTT)

Students may not have two non-credit bearing courses on the same day.

Dropping courses

Students who attend class regularly, turn in all required work and attend tutorials as needed will increase their chance of academic success. If students experience serious academic difficulties and/or have failing grades, a conference between the parent, student and teacher is recommended. Students who follow these steps yet continue to experience consistent academic failure may submit a written request form for a semester schedule change.

Each high school will designate a time period during which request forms may be submitted.

Adding courses

Students may not add a course after the third week of the semester. If there are special circumstances such as new or transfer students or graduating seniors, the principal may approve an addition after this time.

Courses exempt from ineligibility

Students that make below a 70 in a class are suspended from participating in any extracurricular activities sponsored or sanctioned by the District or the UIL. However, some advanced courses are exempt from ineligibility. This means that students who make below a 70 in these advanced classes can still participate in extracurricular activities.

All College Board Advanced Placement (AP) courses, International Baccalaureate (IB) courses and Dual Credit courses are exempt.
