Match both campus and grade. Early-start ADSY covers the elementary campuses below and sixth graders only at the listed middle campuses. Seventh and eighth graders do not take the sixth-grade early start. Lida Hooe Elementary School is Saturday-only, so do not assign its students the ADSY July start from the campus name alone.

Dallas Independent School District ADSY (Additional Days School Year) Calendar 2026-2027
Early-start students at 12 designated elementary campuses and sixth graders at seven designated middle campuses. Lida Hooe is Saturday-only; do not apply the July start to every student at an ADSY-listed campus.
This is additional instruction, not a separate statewide calendar. The current Traditional and ADSY files have the same last day, Thanksgiving, winter and spring recesses, and fall-break dates. The early start and extra instruction are the important differences. Extra-session dates are not reproduced here; use the official ADSY calendar and campus notices for those sessions. Confirm grade and campus eligibility in the official ADSY program page.

Dallas Independent School District calendar questions
When does Dallas Independent School District start and end school in 2026-2027?
Traditional: the first student day is Aug 11, 2026 and the scheduled last student day is May 26, 2027. Dallas ISD students on the Traditional calendar; early-start ADSY groups are listed separately below. ADSY (Additional Days School Year): the first student day is Jul 28, 2026 and the scheduled last student day is May 26, 2027. Early-start students at 12 designated elementary campuses and sixth graders at seven designated middle campuses. Lida Hooe is Saturday-only; do not apply the July start to every student at an ADSY-listed campus.
When is spring break for Dallas Independent School District in 2027?
Traditional: Mar 15, 2027 – Mar 19, 2027. These dates apply only to the stated district calendar, not all Texas schools. ADSY (Additional Days School Year): Mar 15, 2027 – Mar 19, 2027. These dates apply only to the stated district calendar, not all Texas schools.
Which Dallas ISD calendar applies to my school?
Match your campus and grade to the lists on this page. The early-start ADSY program covers designated elementary schools and sixth graders at designated middle schools, not every Dallas ISD student. Lida Hooe is a Saturday-only exception; seventh and eighth graders do not take the sixth-grade early start. Confirm enrollment and any school-specific variation with the campus.
Why do some Dallas ISD students start in July?
ADSY means Additional Days School Year. The district program adds early-start instruction and extra sessions for selected campuses and sixth-grade students. This does not move the first day for all Dallas ISD students.
Do the two Dallas ISD calendars have different spring breaks?
No. The current official Traditional and ADSY files show the same spring break, winter break, Thanksgiving break, fall break and last student day. Their first days and additional instructional sessions differ. The two calendars are shown in separate tables so their scope is not lost.
Where can I download the official Dallas ISD calendars?
The official district calendar entry links to the approved calendar page with both Traditional and ADSY PDFs. Each file is linked with its exact name and fingerprint below. This website is an independent reference, not the Dallas ISD website.
