ADSY Frequently Asked Questions

What is ADSY?

The Additional Days School Year (ADSY) initiative provides formula funding to support school systems with adding up to 30 additional instructional days (beyond a minimum of 175 days) at eligible campuses. Established through House Bill 3 passed by the 86th Texas Legislature in June 2019 (and recently updated by the 89th Texas Legislature via HB 2 in 2025), ADSY launched in the 2020-2021 school year to promote expanded learning time and reduce summer learning loss.

Texas Education Code (TEC) 搂48.0051 establishes that a campus must operate on a base calendar of at least 175 instructional days to be eligible for ADSY formula funding. Newly added subsection (b-1) of TEC 搂48.0051 through HB 2 in 2025 provides the pathway for 戮-day formula funding, which is only available to campuses that reach at least 200 full instructional days.

The tables below outline the minimum number of days and required configurations to generate 陆-day or 戮-day formula funding, effective September 1, 2025:

 
陆-Day Formula Funding for ADSY is available to campuses that:
  • Serve at least one grade level within grades 笔谤别碍鈥8
  • Operate a base calendar with at least 175 instructional days and 75,600 operational minutes, excluding staff development waivers
  • Add 1 to 30 additional half instructional days beyond the base calendar
  • Provide at least two hours of instruction on each ADSY day, delivered by a teacher meeting the school system鈥檚 certification requirements.
  • Host ADSY days separate from the regular instructional calendar days (e.g., ADSY days cannot be hosted in the second part of a regular instructional day)
戮-Day Formula Funding for ADSY is available to campuses that:
  • Serve at least one grade level within grades 笔谤别碍鈥8
  • Have a total of at least 200 full instructional days in the calendar. This total may include ADSY days, but the campus must operate a base calendar with:
    • At least 175 full instructional days
    • A minimum of 75,600 operational minutes, excluding any minutes covered by staff development waivers
  • Add 25 to 30 full additional instructional days beyond the minimum base calendar to reach the 200-day threshold required for 戮-day formula funding eligibility (campuses with more than 175 full instructional days in their base calendar may add only the number of ADSY days needed to reach 200 but may use up to 30 ADSY days to generate funding)
  • Only full ADSY days that provide at least four hours of instruction delivered by a teacher meeting the school system鈥檚 certification requirements will generate 戮-day formula funding
  • Host ADSY days separate from the regular instructional calendar days (e.g., ADSY days cannot be hosted in the 
    second part of a regular instructional day.)
  • Acceptable Calendar Configuration Examples:
    • A campus with 175 full instructional days in its base calendar and 25 full ADSY days meets the 200-day threshold. All 25 full ADSY days would generate 戮-day formula funding.
    • A campus with 180 full instructional days in its base calendar and 25 full ADSY days meets and surpasses the 200-day threshold. All 25 full ADSY days would generate 戮-day formula funding.
    • A campus with 190 full instructional days in its base calendar and 10 full ADSY days would meet the 200-day threshold. The 10 ADSY days would be eligible for 戮-day formula funding, assuming all other ADSY criteria are met.

* Importantly, only ADSY-designated days submitted in PEIMS generate funding. A campus with 200 full regular instructional days but no ADSY designation would not receive ADSY formula funding
