McKinley-Thatcher Elementary School posted Denver^↗ET's second-highest screened elementary math gain from 2022 to 2025.

McKinley-Thatcher's schoolwide math proficiency rose from 36.3% in 2022 to 55.2% in 2025. That 18.9-point gain ranked second among 79 screened Denver elementary schools, behind Goldrick Elementary. Colorado's statewide math rate rose 4.4 points over the same period.

Standout stat: McKinley-Thatcher improved 14.5 points faster than Colorado in math while ending 2025 above Denver and the state.

The gain came from a 2022 rate that was already above Colorado's statewide 2022 math rate. McKinley-Thatcher accelerated from an already solid footing.

A faster climb from stronger footing

The math trajectory is steady enough to stand out. McKinley-Thatcher rose from 36.3% proficient in 2022 to 50.0% in 2023, climbed to 53.8% in 2024, then reached 55.2% in 2025. The school ended the period 22.3 points above Denver's 2025 math rate and 19.3 points above Colorado's.

ELA moved in the same positive direction. McKinley-Thatcher's ELA proficiency rose from 50.6% in 2022 to 68.5% in 2025, a 17.9-point gain. Colorado's statewide ELA rate rose 1.7 points over the same period.

CMAS is Colorado's standards-based state assessment. McKinley-Thatcher's 2022-to-2025 record shows a school that improved quickly while already operating above the state average.

Both subjects ranked near the top

Among Denver elementary schools with at least 30 tested students and published proficiency rates in both 2022 and 2025, McKinley-Thatcher ranked second in schoolwide math improvement, out of 79 screened schools. It ranked third in ELA improvement, out of 80 screened schools.

The pairing separates McKinley-Thatcher from a single-subject rebound. Math rose 18.9 points and ELA rose 17.9 points in the same three-year window.

The ranking screen also keeps the comparison local. Denver's screened elementary schools ranged from a 12.0-point math decline to a 23.2-point math gain. McKinley-Thatcher finished above the districtwide 2025 rate and sat near the top of the distribution.

A stronger 2025 position

The 2025 standing chart shows the difference between rapid recovery and strong current performance. McKinley-Thatcher's 55.2% math proficiency topped Denver's 32.9% and Colorado's 35.9%. Its 68.5% ELA proficiency topped Denver's 41.9% and Colorado's 44.8%.

CMAS is one measure of academic performance. CDE says participation rates should be considered because they affect how representative reported results are likely to be. The screen uses schoolwide rows, which match the Denver and statewide comparisons used here.

McKinley-Thatcher paired a fast improvement rate with a 2025 proficiency level above district and statewide benchmarks in both subjects.

The data establish the school's 2022–2025 gains; they do not establish how durable that position will be as cohorts change.
