Texas Rising Star
Texas Rising Star 4-star of a possible 4
A quality rating the state awards after an on-site assessment. Four stars is the highest.
In effect since October 14, 2026. From the state's provider report of October 28, 2026.
Where this is
A map of this address loads when you ask for it. Nothing is requested from the map host until then, so opening this page does not tell anyone which program you were reading about.
The pin is where the US Census geocoder placed this address. About one in eight is interpolated along a street rather than resolved to a building, so treat it as the right block rather than the right doorway. How we source this.
What inspectors checked
Texas HHSC records how many individual standards it evaluated in each area of the rules, and how many it found violated. Across 22 areas it checked 8,623 standards at Montessori School of Sugar Land Sienna between June 27, 2022 and October 6, 2026 and recorded 81 violations. Those correspond to the citations listed above that were recorded from 2021 onward; anything older than that is in the citation list but not in these counts.
The 22 areas, one by one
| Area of the rules | Visits | Standards checked | Violated |
|---|---|---|---|
| Scope, administration, and communication | 7 | 853 | 0 |
| Record keeping | 8 | 881 | 6 |

| Pools | 6 | 168 | 0 |
| Fire safety | 6 | 404 | 3 |
| Transportation | 7 | 343 | 6 |
The table adds up to 8,476 of those standards. The remaining 147, including 50 of the violations, were recorded under the state's own catch-all heading, “Individual Standards Evaluated”, which names no area. They are reported here rather than folded into an area above, because the state did not say which area they belong to and we are not going to decide for it.
A high number of standards checked is not a compliment and a low one is not a criticism: how many apply depends on a program's size, its ages served and what the inspector was there to look at. We publish the two counts the state published and do not turn them into a score. This data begins in 2021, which is later than the inspection history above it.

Ask about an opening
This goes to Montessori School of Sugar Land Sienna and nobody else. They reply to you directly: we do not sit in the middle of it, and we never pass your details on or sell them.
Tell me about new inspections
One short message each time Texas HHSC records an inspection here, saying that it happened and linking to the record. We do not tell you what the inspector found: a finding without whether it was corrected is misleading, and that pair belongs on the page rather than split across an email.
We ask for nothing but the address, and we send a confirmation first. Your list is never shown to this program, never sold, and every message has a link to stop. An inspection is routine: programs are visited on a schedule and after a complaint, and a visit is not a finding.
State inspection record
HHSC records 58 visits to this operation since October 2017, most recently on October 6, 2026, and 81 citations.
3 of those visits began with Montessori School of Sugar Land Sienna reporting something to the state itself rather than HHSC finding it. We publish that because it is part of the record and the state records it separately, not because it is good or bad: a program with none may have had nothing to report. 3,674 of the 12,933 programs listed here have at least one.

About this record
Every figure on this page comes from the Texas HHSC Child Care Regulation open data published at data.texas.gov, reproduced as the state recorded it. We do not grade, score or rank programs. A citation is a finding by a state inspector on a given day; it is not a judgment about a program today, and the correction status beside each one is part of the record. This page reflects data retrieved on November 8, 2026. Full methodology.
