ADSY Calendar

The ROISD 2026-2027 Additional Days School Year (ADSY) Calendar is an extension of the 175-day calendar for up to 30 additional instructional days for identified students. We will notify families in the spring of students who need to attend summer programming.

The ADSY Calendar blocks out all dates for summer school, including elementary, middle, and high school, plus summer school for Emergent Bilingual (formerly English as a Second Language).

• Elementary and Middle School Summer School - June 2-24, Monday-Thursday
• High School Summer School – June 7-24, Monday-Thursday
• Emergent Bilingual – June 2-25, Monday-Friday
