Tomball ISD 2027-2028 School Calendar

Students begin Tuesday, August 17, 2027. Staff development and new-teacher dates earlier in August are not regular student classes.

Thursday, May 25, 2028, is the scheduled last day, with early release at all schools. May 26 is reserved for make-up instruction if needed, so confirm the final schedule before relying on that Friday as a day off.

The scheduled school year ends with early dismissal on Thursday, May 25, 2028. Friday, May 26, is reserved for possible make-up instruction. Confirm whether that day will be used before making summer travel plans.

Yes. The official PDF states that it was Board-approved on February 10, 2026. It is available from the district’s Instructional Calendar page.

No. Monday, September 6, 2027, is a staff and student holiday. Students return Tuesday, September 7.

Students are off October 7–11. October 7–8 and October 11 are staff-development/workdays, with the weekend in between. This is a five-day stretch without classes, rather than a separately named Fall Break on the PDF. Classes resume October 12.

Yes. October 11 is a staff-development/workday and a student holiday. It follows the October 7–8 staff days and the weekend; students return Tuesday, October 12.

No. Reporting periods end October 6 and December 17, 2027, and March 10 and May 25, 2028. Only December 17 and May 25 are all-school early-release dates. October 6 and March 10 remain regular school days.

No. November 1–2 are staff-development/workdays with no student classes. Students return Wednesday, November 3.

Thursday, November 11, 2027, is a scheduled school day. The instructional calendar does not list it as a student holiday.

Thanksgiving holidays run November 22–26, 2027. Including both surrounding weekends, students have November 20–28 off and return Monday, November 29.

The official winter holidays are December 20–31, 2027. January 3–4 are additional student holidays for staff development or workdays, and students return January 5.

Students have 18 consecutive calendar days without classes, December 18, 2027, through January 4, 2028. December 17 is still an attendance day with early dismissal.

Classes resume Wednesday, January 5, 2028. January 3 and 4 are staff days with no student classes.

Yes. Monday, January 17, 2028, is a staff and student holiday. The next scheduled school day is Tuesday, January 18.

No. The published calendar lists February 21 as a staff and student holiday, not a possible make-up day. The preceding Friday, February 18, is different: it may be used for make-up instruction. Check district announcements for any later changes.

February 18 is scheduled for staff development or work and is a student holiday unless needed for make-up instruction. Check the district’s decision before planning a four-day Presidents Day weekend.

Within the student year, the dates are October 7–8 and 11, November 1–2, January 3–4, February 18 and March 20. February 18 and March 20 may become school days if needed for make-up instruction. Pre-opening staff dates do not mark the start of student classes.

Spring Break is March 13–17, 2028. With the surrounding weekends, students have March 11–19 off. The following Monday, March 20, is a separate staff day and possible make-up date.

The published schedule has students returning Tuesday, March 21, after the March 20 staff day. If Tomball ISD uses March 20 for make-up classes, students would return that Monday instead. Confirm the date with the district.

Students have nine consecutive days without classes, March 11–19, including weekends. March 20 is scheduled as a student holiday but may be used for make-up instruction. If it remains a day off, the break extends to ten days and students return March 21. If the district uses March 20 for classes, students return that Monday.

Yes. Friday, April 14, 2028, is a staff and student holiday. It is separate from the March Spring Break and is not listed as a make-up date.

Monday, April 17, 2028, is a scheduled school day. The calendar provides a holiday on Good Friday, April 14, but not the following Monday.

The calendar reserves February 18, March 20 and May 26, 2028, if make-up instruction is needed. These are scheduled student holidays or staff days that may become attendance days. No activation order is specified.

The all-school early-release dates are Friday, December 17, 2027, and Thursday, May 25, 2028. Students attend on both dates, and May 25 is the published last day.

Thursday, December 16, 2027, and Wednesday, May 24, 2028, are additional early-release days for high schools. Other school levels follow their regular schedules. High schools also release early on the two all-school dates, December 17 and May 25.

The approved instructional calendar does not specify dismissal times. Ask your campus for the 2027–28 early-release schedule rather than use regular dismissal times or a previous year’s pickup time.

The four end dates are October 6 and December 17, 2027, and March 10 and May 25, 2028. December 17 and May 25 have all-school early release; October 6 and March 10 are regular school days.

Report-period boundaries are printed on the calendar, but online report-card release dates are not. Use Home Access Center and campus communications to check when reports become available.

We calculate 170 planned student attendance days from the published dates. This total is not stated in the official PDF. Early-release days count as attendance days, while possible make-up dates and later district changes may affect the final schedule.

As of October 22, 2026, the district's published Bell Schedules page covers 2026–27, not 2027–28. The 2027–28 instructional calendar lists school dates and early-release days but does not provide campus bell times. Check the district's Bell Schedules page for a year-specific update before arranging arrival or pickup.

The district’s general closing procedure says the website will be updated by 6 a.m. if severe weather closes schools. Automated calls, texts, emails, social media and local television also carry updates. No announcement is issued when schools keep their regular hours; follow any later instructions from the district.

The official PDF is linked on this page and under Printable 2027-28 Calendars on the district’s Instructional Calendar page. Choose Instructional Calendar 2027-28 when checking dates for this school year.

Friday, December 17, 2027, is the last scheduled student day before Winter Break, and all schools release early. Winter Break runs December 20–31, followed by January 3–4 staff days. Students return January 5, 2028.

March 20 is scheduled as a staff-development/workday and student holiday, but it is also a possible make-up day. If the district uses it for instruction, students return after Spring Break on March 20. Otherwise, classes resume March 21.

No. The 2027–28 instructional calendar does not list graduation ceremony dates or times. Check Tomball ISD's Graduation page and the relevant high school for ceremony information rather than assuming graduation will take place on the last instructional day.

Check Tomball ISD's latest announcements and your child's campus messages before making plans. The approved calendar lists possible make-up dates but does not confirm which, if any, will be used. Pay particular attention to March 20, since using that date would change the return from Spring Break.

Tomball ISD's Instructional Calendar page offers a Calendar Feeds / Live Subscription option with a separate Instructional Calendar feed. Check the feed for the dates currently available. The ICS download on this independent page may not update automatically when the district makes changes.
