School calendar overview

The 2026–2027 Rio Grande Valley school calendar begins Aug 17, 2026 and ends May 27, 2027.

Before you plan

This independent calendar reference is not operated by IDEA Public Schools. Confirm bell times, transportation, meals, testing, campus events, and same-day schedule changes with the Rio Grande Valley campus your child attends.

What to know

IDEA Rio Grande Valley begins August 17, 2026 and ends May 27, 2027; other IDEA regions use different opening and closing dates.
The October professional-development day and two IDEA holidays produce a continuous student break, even though the entries have different labels.
The Rio Grande Valley quarter-ending dates are October 16, 2026, January 8, 2027, March 25, 2027, and May 27, 2027.
January 4-5 is kept separate from the official winter holiday so the source wording remains clear while the January 6 student return is still easy to plan around.

Editorial summary

Planning around the IDEA Rio Grande Valley 2026-2027 calendar

Rio Grande Valley students begin classes Monday, August 17, 2026, and finish Thursday, May 27, 2027. The October 8 professional-development day leads into IDEA holidays on October 9 and 12, so families have a continuous Thursday-through-Monday pause. Quarter one ends October 16. Thanksgiving week is off in full, followed later by a December 21-January 1 winter holiday.

Students do not return immediately after New Year’s Day: professional development on January 4-5 pushes the first day back to Wednesday, January 6. Spring break is March 15-19. The March 26 IDEA Holiday and March 29 training day make a second, shorter four-day break later in the month.

Common questions

IDEA Public Schools 2026–2027 Rio Grande Valley calendar FAQs

When is the first day of school for IDEA RGV in 2026-2027?

Students begin Monday, August 17, 2026. The Student-Family Engagement Day happens earlier, but it is not the first regular day of classes.

When is the last day of school for IDEA RGV?

The final student day is Thursday, May 27, 2027. It is also the end of the fourth quarter; the teacher workday printed after it is not a student attendance day.

What are the IDEA RGV Thanksgiving break dates?

Students have no regular classes Monday, November 23, through Friday, November 27, 2026. With the surrounding weekends, they leave after class November 20 and return Monday, November 30.

When is winter break for IDEA RGV in 2026-27?

The regional calendar marks December 21, 2026, through January 1, 2027, as an IDEA Holiday.

When do RGV students return after winter break?

Students return Wednesday, January 6, 2027. January 4-5 are separate no-school professional-development days after the IDEA Holiday ends.

When is spring break for IDEA RGV in 2027?

The regional calendar marks March 15-19, 2027 as an IDEA Holiday.

When do RGV students return after spring break?

The IDEA Holiday ends Friday, March 19, and students return Monday, March 22, 2027.

How long is the October break for RGV students?

Students have no classes Thursday, October 8, through Monday, October 12. Professional development and two IDEA holidays connect across the weekend, and regular classes resume Tuesday, October 13.

When is Student-Family Engagement Day, and is it the first regular school day?

The RGV calendar marks Friday, August 7, 2026 as Student-Family Engagement Day. It is not the first regular school day, and the PDF does not publish hours or a campus agenda.

Does this calendar apply to every IDEA campus in Rio Grande Valley?

This is the official regional academic calendar for IDEA campuses in Rio Grande Valley. Campus-specific testing, events, bell schedules, transportation details, or emergency schedule changes may not appear on the regional calendar.

Where can families download the official IDEA RGV calendar?

Use the official PDF link on this page or open IDEA Public Schools’ Academic Calendars page and select the 2026-2027 Rio Grande Valley calendar.

Does the official IDEA RGV calendar include Spanish?

Yes. The official regional PDF includes calendar pages in both English and Spanish.

Can the 2026-2027 dates change because of weather?

Yes. The PDF says the calendar may change in response to nearby school districts and inclement weather. Families should check IDEA alerts and campus messages before relying on a date affected by a closure.

Does the RGV calendar have a February half day?

No. The Rio Grande Valley PDF does not mark a February half day. The February 25 half day appears on Brownsville’s separate calendar, so RGV families should not carry that date over to their campus.

Are RGV students off March 26 and March 29, 2027?

Yes. March 26 is an IDEA Holiday and March 29 is a no-school professional-development day. Students return Tuesday, March 30.

When do IDEA RGV grading periods end in 2026-27?

IDEA RGV’s four quarter-ending dates are October 16, 2026; January 8, March 25, and May 27, 2027. The fourth quarter ends on the last student day.

Source and scope

About the IDEA Public Schools 2026–2027 Rio Grande Valley calendar

Data source

This page uses IDEA Public Schools’ official 2026-2027 Rio Grande Valley Academic Calendar PDF, issued January 20, 2026, plus the network’s Academic Calendars page. Both were checked October 5, 2026. The PDF supplies student-year boundaries, IDEA holidays, no-school training days, quarter endings, and any region-specific schedule symbol.

How dates are handled

Dates were checked against the visible month grid and printed event labels. Staff development before August 17, 2026 and the teacher workday after May 27, 2027 were excluded because they fall outside the student year. Separate no-school entries are described as one continuous break only when every intervening calendar day connects them.

Updates

IDEA notes that the Rio Grande Valley calendar can change for surrounding-district updates or inclement weather. A later official regional PDF or campus notice should take priority over this record, especially when a closure affects transportation, make-up instruction, or a planned return date.
