Contents

Staying on top of the La Serna High School bell schedule for the 2025-2026 school year is essential for every student, parent, and staff member. The Whittier Union High School District (WUHSD) implements several different schedules throughout the week and school year—including the standard Regular Day, the weekly Friday Late Start, and special Minimum Day schedules—making it crucial to have the current times readily available.

This article provides the most current and confirmed timing for La Serna’s academic year, ensuring you know exactly when classes begin, when the all-important Nutrition Break occurs, and when the school day officially ends. The information below is based on the official 2025-2026 schedule documents released by La Serna High School.

The Core: La Serna High School Regular Bell Schedule (Monday–Thursday)

The Regular Bell Schedule is the backbone of the La Serna High School week, running from Monday through Thursday. This schedule is designed for full instructional days and includes the popular option of Period 0 for students with an expanded course load. Knowing the exact start and end times for the first few periods is vital for a smooth start to the day.

The Regular Day schedule is structured to maximize instructional time, with periods typically lasting around 50 to 54 minutes each, punctuated by a mid-morning Nutrition Break.

Key Start Times & Confirmed Periods (Regular Schedule)

The following table outlines the confirmed start and end times for the beginning of the Regular Day schedule, which operates on Monday, Tuesday, Wednesday, and Thursday:

Period Start Time End Time Duration
Period 0 7:24 AM 8:24 AM 60 mins
Period 1 8:30 AM 9:20 AM 50 mins
Period 2 9:26 AM 10:20 AM 54 mins
Nutrition Break 10:20 AM 10:35 AM 15 mins
Period 3 10:41 AM 11:35 AM 54 mins
Lunch 11:35 AM 12:15 PM 40 mins
Period 4 12:21 PM 1:15 PM 54 mins
Period 5 1:21 PM 2:15 PM 54 mins
Period 6 2:21 PM 3:15 PM 54 mins

*Note: The times for Periods 3-6 are based on standard WUHSD period lengths following the confirmed early times and breaks. Always verify the full schedule on the official La Serna High School website.

The Friday Late Start Schedule: Teacher Collaboration Time

Every Friday, La Serna High School operates on a Late Start schedule to facilitate crucial Teacher Collaboration Time. This weekly late start allows faculty to engage in professional development, curriculum planning, and WASC preparation, directly benefiting student learning and instructional quality. This means students get a later start to their day, but the schedule is compressed.

Confirmed Friday Late Start Times

The Late Start schedule moves the first instructional period back by over half an hour, with the morning dedicated to staff collaboration. The total duration of class periods is also slightly shortened to accommodate the later start and maintain the end-of-day timeline.

  • Teacher Collaboration Time: 8:00 AM – 8:55 AM (55 mins)
  • Period 1 Start Time: 9:00 AM
  • Period 1 End Time: 9:48 AM (48 mins)

Students who rely on the LSHS Bus Schedule should pay close attention to the adjusted bus transportation times for the Late Start day, as they are specifically modified to align with the later Period 1 start.

Special Schedules: Minimum Days, Finals, and Assemblies

Throughout the 2025-2026 WUHSD Academic Calendar, La Serna High School will utilize various modified schedules for specific events. These special schedules are typically condensed, serving as a "LATE START / EARLY OUT" format, and are most frequently implemented for semester finals, staff development days, or special assemblies.

Minimum Day Schedule (Finals & Special Events)

The Minimum Day Schedule is a highly condensed format that allows for an early release, often used during the last days of the semester for Finals Minimum Day Schedule testing. A recent example of this structure shows a significantly shorter class duration of approximately 35 minutes per period, starting later in the morning.

For example, a typical Minimum Day structure begins with Period 1 starting at 9:00 AM and ending at 9:35 AM, followed by Period 2 from 9:41 AM to 10:16 AM.

Key Takeaways for Minimum Days:

  • Late Start Time: Classes begin at 9:00 AM or later.
  • Shorter Periods: Instructional periods are significantly reduced (e.g., 35 minutes).
  • Early Out: The school day concludes much earlier than the regular 3:15 PM end time.
  • Finals Schedule: During finals week (e.g., December 17-19), the schedule is typically a Minimum Day format, often covering only two or three periods per day.

Assembly and Back-to-School Night Schedules

La Serna High School also has specific, unique schedules for special events like the annual Back-to-School Night and school-wide assemblies. These schedules, such as the confirmed "assembly bell schedule 8.27.2025" and "back to school night bell schedule 8.27.25," are usually released closer to the event dates and involve minor time adjustments to accommodate the special programming without disrupting the core instructional minutes.

It is always recommended to check the official La Serna High School news and announcements page for the specific times on these unique days.

Topical Authority and School Contacts

As part of the Whittier Union High School District (WUHSD), La Serna High School maintains its official bell schedules on the district's platform. This ensures that the information is consistent and up-to-date for all stakeholders, including parents, students, and community members.

If you encounter any discrepancies or require further clarification on the 2025-2026 bell schedules—especially concerning specialized schedules like the Friday Extended Late Start (used for WASC or other development days) or specific bus schedules—the official school office is the best resource.

The administration and guidance departments utilize the bell schedule as part of a larger system, including the Preventions & Interventions Pyramid framework, to manage student attendance and support. Understanding the bell schedule is the first step in ensuring a successful academic year at La Serna.
