School calendar overview

The 2026–2027 ADSY school calendar begins Aug 12, 2026 and ends Jul 15, 2027.

Before you plan

The calculated attendance count does not establish that every child must attend all summer sessions. Participation rules, separate summer hours, buses and meals are not given. June 17 is marked as a holiday while the holiday list names June 19 as Juneteenth; no holiday name is inferred for June 17. February 15 remains conditional.

Listed early-release dates: 2 dates; Calculated from official datesCounted from early-release entries on this calendar. An early-release date still counts as a student attendance day.
Longest listed break: 17 consecutive days; Calculated from official datesDec 19, 2026–Jan 4, 2027, including weekends. The stretch contains 11 confirmed no-school weekdays.
Long weekends: 11; Calculated from official datesCounts three- or four-day no-school stretches formed by a weekend plus one or two confirmed weekday closures. Longer school breaks are excluded.
Full-week breaks: 4 breaks; Calculated from official datesCounts continuous no-school stretches containing at least five confirmed weekdays without regular classes. Adjacent holidays and weekends remain part of the same break.

What to know

ADSY retains the August 12 regular start but continues with additional session dates through July 15.
February 16-19 are class dates on ADSY, unlike the regular calendar's Mid-Winter Break.
June 3 is both a report-card date and a marked ADSY session; it does not cancel attendance.
The 25 marked summer dates are split into actual attendance blocks rather than a continuous June 1-July 15 event.
June 17 is marked as a holiday, while the printed list names June 19 as Juneteenth; no unsupported holiday name is assigned to the June 17 closure.
July 15 is the final ADSY attendance date and is not marked for early release.

Editorial summary

Spring ISD ADSY dates for Bammel, Major and Heritage

Bammel Elementary, Major Elementary and Heritage Elementary use Spring ISD's ADSY calendar. Their regular student schedule opens August 12, 2026, and the fourth grading period ends May 28, 2027. Fall Break is October 12-16, Thanksgiving Break is November 23-27 and Spring Break is March 15-19. January 4 is a no-student staff day after Winter Break, with students returning January 5.

The regular calendar's February Mid-Winter Break does not carry over to ADSY: February 16-19 are class dates. February 15 is named Presidents Day and may be used for make-up instruction, so its attendance status depends on whether it is used. November 2 and 3 are no-student staff-development and conference dates. December 18 and May 28 are half days; the three named elementary campuses dismiss at 12:55 p.m.

Additional ADSY sessions are scheduled June 1-3, June 7-10, June 14-16, June 21-24, June 28-July 1, July 6-8 and July 12-15. There are no ADSY sessions on June 4, 11, 17, 18 or 25, or July 2, 5 or 9. July 15 is the final ADSY day and is not marked for early release. These sessions are separate from the tentative summer-school and Pre-K-K EB program dates.

Common questions

Spring ISD 2026–2027 ADSY calendar FAQs

Which Spring ISD schools use the 2026-2027 ADSY calendar?

The PDF names Bammel Elementary, Major Elementary and Heritage Elementary. It does not name Bammel Middle School. Ponderosa Elementary and Bailey Middle have a separate ACE calendar; other families should check the regular district calendar.

What does ADSY mean in Spring ISD?

ADSY stands for Additional Days School Year. The 2026-2027 Spring ISD ADSY calendar applies to Bammel, Major and Heritage elementary schools.

When do regular classes begin at Spring ISD ADSY campuses?

The regular first day is Wednesday, August 12, 2026, the same as the district instructional calendar. June 1 is the start of the additional 2027 ADSY sessions, not the beginning of the regular school year.

When is the regular last day, and when does ADSY finish?

The regular grading year ends Friday, May 28, 2027, with early release. The calendar then marks additional June-July ADSY dates, ending Thursday, July 15. July 15 is the official ADSY last day and is not marked for early release.

How many attendance dates are shown on the Spring ISD ADSY calendar?

The published schedule contains 201 calculated attendance dates: 176 during the regular grading year and 25 additional summer dates. Spring ISD does not print this as an annual total. February 15 is conditional, and the count does not establish each student’s summer participation requirements. With all other published dates unchanged, using February 15 as a make-up day would bring the scheduled count to 202.

What are the marked June and July ADSY session dates?

Additional ADSY sessions are June 1-3, June 7-10, June 14-16, June 21-24, June 28-July 1, July 6-8 and July 12-15. Those blocks contain 25 marked dates. The June 1-July 15 caption is an overall span, not a continuous daily class event.

Are the additional ADSY sessions optional or required?

The PDF marks ADSY attendance dates but does not state eligibility, enrollment rules or whether each student must attend. Do not assume optional or universal participation from the listed dates alone. Ask Bammel, Major or Heritage for instructions that apply to your child.

Do ADSY students attend on Fridays in June and July?

No ADSY sessions are scheduled on June 4, 11, 18 or 25, or July 2 or 9. The PDF’s district-closure legend explicitly names July only; the absence of June Friday sessions does not establish June office hours.

Is June 17 an ADSY attendance date?

No. June 17 is marked as a holiday rather than an ADSY attendance day. The calendar separately lists June 19 as Juneteenth, so it does not identify the June 17 closure by name.

Is there an ADSY session on July 5, 2027?

No. July 5 is marked as a holiday, with no ADSY session. The next session is July 6, following the July 2 Friday closure and the intervening weekend.

When is fall break for Spring ISD ADSY campuses?

Fall Break is October 12-16, 2026, the same week as the regular district calendar. The next class date is October 19. Do not substitute ACE's shorter October 14-16 break for the ADSY campuses.

When is Thanksgiving break on the ADSY calendar?

Bammel, Major and Heritage are off November 23-27, 2026. The next regular class date is Monday, November 30. This is the same Thanksgiving week as on the other two calendars.

When is Winter Break for Spring ISD ADSY campuses in 2026-2027?

Winter Break runs December 21, 2026 through January 1, 2027. January 4 is a separate professional-development day with no students, and classes resume January 5.

When do ADSY students return after winter break?

Students return Tuesday, January 5, 2027, when the second semester begins. January 4 is a professional-development day with no students.

Do ADSY campuses have the February 15-19 Mid-Winter Break?

No. The ADSY calendar lists February 15 as Presidents Day, with a possible make-up day. February 16-19 are regular class dates. The full Mid-Winter Break and selected-student intervention entries on the district instructional calendar do not apply to this ADSY calendar.

Is February 15 a guaranteed day off for ADSY students?

No. February 15 is listed as Presidents Day and also marked Make-up Day (if needed). Follow district and campus notices before treating it as a holiday; the PDF does not show February 16-19 as a break.

When is Spring Break for ADSY campuses in 2027?

Spring Break runs March 15-19. The next regular class date is March 22. March 26 is a separate Spring Holiday, with regular classes scheduled on the intervening March 22-25 dates.

Which dates are early release for Spring ISD ADSY campuses?

December 18, 2026, and May 28, 2027, are early-release days. December 17 and May 27 are not early-release dates for ADSY campuses. July 15 is the final ADSY day and is not marked for early release.

What time do Bammel, Major and Heritage dismiss on half days?

Bammel, Major and Heritage dismiss at 12:55 p.m. on December 18 and May 28. This is the elementary early-release time; middle and high school dismissal times do not apply to these campuses.

Are November 2 and 3 student holidays on ADSY?

Yes. November 2 is marked teacher professional development with no students, and November 3 is parent-teacher conferences with no students. The next regular class date is November 4.

When are report cards and IEP goal updates on ADSY?

They are listed for October 9, January 8, March 12 and June 3. June 3 comes after the regular grading-year finish but is also an ADSY attendance date. A report-card date does not cancel that session.

What are the regular ADSY grading periods?

The four grading periods are August 12-October 2, October 5-December 18, January 5-March 5 and March 8-May 28. March 8 starts the fourth period before the March 15-19 Spring Break; a grading-period boundary is not a report-card distribution date. The extra June-July sessions are shown separately rather than as a fifth grading period.

When is STAAR/EOC testing marked on ADSY?

The calendar marks December 7-11 and 14-18, then April 6-9, 12-16, 19-23 and 26-29 for STAAR/EOC testing. These are marked testing dates, not a daily test requirement for every student. Use your campus's grade and subject assignments.

What are the regular hours for the named ADSY elementary campuses?

The elementary class day is 8:05 a.m.-3:25 p.m., with first-bell transition from 7:55-8:05 a.m. The listed half days end at 12:55 p.m. The PDF does not give a separate timetable specifically for the June-July ADSY sessions.

Does ADSY provide a summer transportation or meal schedule?

The PDF does not give bus routes, pickup times, meal arrangements or separate summer session hours. Get those details from Bammel, Major or Heritage before attending the additional dates; the regular bell-time table is not a summer service plan.

Are ADSY Days the same as tentative summer school?

The PDF separately lists June 8-July 1 for Pre-K-K EB students and June 8-July 9 as Tentative Summer School. These are program date spans, not a published daily attendance schedule or a requirement for every student. Check campus notices for participation and actual session dates. The additional ADSY sessions have their own June 1-July 15 schedule and should not be replaced with those other program spans.

Is Memorial Day included between the regular year and ADSY sessions?

Yes. Monday, May 31, 2027, is a holiday between the May 28 regular finish and the June 1 first ADSY session. It is not an ADSY attendance day.

Where can I download the official Spring ISD ADSY calendar?

Use the ADSY PDF naming Bammel, Major and Heritage elementary schools linked here or select it from Spring ISD's Printable Calendars page. ACE and the regular instructional calendar are separate files with different attendance dates.

Source and scope

About the Spring ISD 2026–2027 ADSY calendar

Data source

The district-hosted ADSY PDF, revised August 10, 2026, names Bammel, Major and Heritage elementary schools. Its dated summer schedule was checked visually against the legend.

How dates are handled

The regular grading year ends May 28; ADSY attendance continues through July 15. Consecutive marked summer attendance dates are grouped into derived blocks. July 15 is counted once. June Fridays are scoped program-not-scheduled dates with no ADSY sessions, but the district-closure legend names Fridays in July only, so the June entries do not claim district-office closure. Grouped or inferred schedule entries remain in events for attendance calculations and are labelled Calculated from calendar in the table, monthly view and subscription export; they do not claim official event titles.

Updates

The three district-hosted PDFs were reviewed visually and through text extraction on October 6, 2026. Their revision dates are preserved in the source metadata. The PDFs do not provide approval dates or revision histories. Later district or campus updates may alter make-up arrangements.
