2024 Legislative Update

House Bill 227 was introduced during the 2024 legislative session to cap the size of elementary school classes at 20 students. The bill would phase in this 20-student cap over six years, one grade level per year, allowing ample time for districts to plan for funding, space, and staff.

House Bill 227 was drafted by Think New Mexico and is sponsored by a bipartisan team of legislators including House Majority Caucus Chair Raymundo Lara (D-Las Cruces) and Representatives Tanya Mirabal Moya (R-Los Lunas), Patricia Roybal-Caballero (D-Albuquerque), and Jack Chatfield (R-Mosquero), all of whom serve on the House Education Committee.

Smaller classes allow teachers to spend more time with each individual student, amplifying the benefits of the extended learning time enacted last year. Research shows that achievement gaps are reduced when low-income and minority students remain in small classes over several years. Smaller classes also make it easier for teachers to build strong relationships with students and their families, which is the most effective strategy for addressing chronic absenteeism. Finally, reducing class size also reduced teacher burnout and attrition, keeping good teachers in the profession longer.

This reform is strongly supported by New Mexicans. A November 2022 poll commissioned by Think New Mexico and overseen by UNM Professor Dr. Gabriel Sanchez found that 96% of New Mexico voters consider class size important to student success, and 83% support of New Mexico voters support capping the size of K-6 classes at 20 students.

Current state law caps kindergarten classes at 20 students and sets “average” class sizes of 22 for grades 1-3 and 24 for grades 4-6. Yet when Think New Mexico examined statewide enrollment data from the Public Education Department, we found that 27% of elementary classrooms exceeded those limits in the 2022-2023 school year.

Unfortunately, House Bill 227 did not receive a message from the governor, meaning it could not be considered during this year’s short, 30-day legislative session. We look forward to supporting this essential reform in 2025.

2023 Legislative Update

Smaller class sizes allow teachers to provide more personalized instruction, which is particularly important for the at-risk students who need the most support. Since 1986, New Mexico has capped class sizes in statute, but the Public Education Department has frequently provided waivers allowing for larger classes.

During the 2023 legislative session, Think New Mexico supported House Bill 413, which was developed in collaboration with our Education Reform Director Mandi Torrez, proposes an innovative approach that sets lower class size limits for schools that have high populations of at-risk students. It also restricts the use of waivers to exceed class size limits for all students.

House Bill 413 received a very favorable hearing in the House Education Committee, but the committee chose not to move it forward because there was not money included in this year’s budget to reduce class sizes. However, the committee was eager to make this reform a priority for next year, and we plan to work with them to get this legislation enacted in 2024.


The research overwhelmingly shows that students tend to do better in smaller, more personalized learning environments. Perhaps counterintuitively, smaller (or at least medium-sized) districts and schools are also often more cost-efficient as well as more effective for student performance.

Smaller Schools

Smaller SchoolsNew Mexico’s graduation rate ranks second from the bottom of the 50 states and the District of Columbia. Only 54.1% of New Mexico’s children graduate from high school, compared with a national average of 70.6%. An average of 77 students drop out each school day across New Mexico—nearly 14,000 per year.

Decades of research have shown that smaller schools have higher graduation rates, higher student achievement, lower levels of student alienation and violence, and higher levels of satisfaction among students, parents, principals, and teachers. Small schools also dramatically improve the performance of low-income children, which helps to narrow the persistent achievement gap.

The most effective high school size, according to the research, is 600-900 students. Yet in the 2021–2022 school year, more than half of New Mexico ninth graders entered high schools with populations larger than 1,000 students, and the state continues to spend millions of dollars annually building large schools.

Small schools are not only better for students, they also cost less to build and operate. Researchers have found that the most efficient schools are those serving 300-900 students. Schools larger than this experience “diseconomies of scale”: inefficiencies and increased costs that result from increases in bureaucracy, security, and transportation. In addition, if the operational cost of a school is calculated “per graduate” rather than “per student,” small schools are substantially more efficient than large schools because their dropout rates are much lower.

The capital costs of small schools can also be far less per student than those of large schools if the small schools are designed to take advantage of community educational resources like gymnasiums, pools, libraries, and sports fields, rather than duplicating these facilities. Several New Mexico charter schools have successfully applied this community-based model, at a savings of millions of taxpayer dollars.

Think New Mexico recommends that the legislature and governor enact legislation limiting the size of new schools built in New Mexico at no more than 400 students for elementary and middle schools and no more than 900 students for high schools.

Smaller Districts

Research going back more than four decades, in jurisdictions ranging from California to West Virginia, has found that larger school districts tend to have negative impacts on student achievement, particularly for students from low-income families.

While most New Mexico school districts are small, Albuquerque Public Schools (APS) is the 35th largest school district in the nation according to the National Cen-ter for Education Statistics, with an enrollment of 72,088 students as of 2021 (not counting the district’s charter schools).

Sadly, APS students underperform the rest of the state. As a 2022 analysis by the Legislative Finance Committee (LFC) put it, APS is plagued by “low proficiency rates, large achievement gaps, lower post-pandemic learning growth, lagging high school graduation rates, and falling college enrollment and readiness.” Because about a quarter of all students in New Mexico attend APS, the underperformance of this district weighs heavily on the entire state—and likewise, improving the performance of APS students would lift the entire state’s education rankings.

The enormous size of APS makes it impossible to govern well. For example, with 143 schools (not counting the charters), even the most active and committed superintendent could not visit all of them more than once during a school year.
Similarly, each APS school board member represents over 90,000 people. Compare this to the state’s most successful small districts where each board member represents just a few hundred to a few thousand New Mexicans. As with the superintendent, it would be impossible for even the hardest-working, most dedicated school board member to effectively communicate with and be responsive to over 90,000 people. Deconsolidating APS into smaller districts would allow board members to be closer to their constituents, better representing the diverse interests of different parts of the city.

Deconsolidating APS would also likely results in cost savings, as decades of research have shown that, once school districts exceed a certain size, they begin to suffer from diseconomies of scale, becoming more expensive to operate than medium-sized districts.

According to the most recent data available from PED, the average cost per pupil of school districts enrolling 15,001–25,000 students, the size tier just below APS, is $7,284. The cost per pupil at APS is $7,532. That $248 difference, when multiplied across APS’s 72,088 students, adds up to nearly $18 million.

Think New Mexico recommends that the legislature and governor enact a law requiring any district larger than 35,000 students to place a question on the next election ballot asking the public whether they would like to deconsolidate it into smaller districts.

Smaller Classes

The research indicates that smaller class sizes can result in meaningful long-term improvements in student outcomes. Studies and surveys have also shown that smaller class sizes have a positive impact on the working environment for teachers. Smaller classes reduce teacher stress and allow teachers to provide more personalized instruction, which is particularly important as they deal with increased behavioral problems in the wake of the pandemic.

Since 1986, New Mexico has capped class sizes in statute. Currently, those caps are 20 students for kindergarten; 22 for grades 1–3; and 24 for grades 4–6. In high school, the class size caps are specific to English courses, and are 27 students for grades 7–8 and 30 students for grades 9–12.

However, since at least 2005, the state has issued waivers to allow classes to exceed these caps.

Think New Mexico recommends that the legislature and governor prohibit the granting of waivers of class size limits and keep the student-teacher ratio at a manageable level.

Legislative Update

Smaller SchoolsDuring the 2009 legislative session, Think New Mexico championed legislation to incentivize the state’s school districts to build smaller schools. The bill (Senate Bill 255) passed the Senate 28-11, but ran out of time in the House. In 2011, Think New Mexico’s legislation (Senate Bill 2) was unanimously approved by both the Senate Education and Senate Finance Committees. In 2012, Think New Mexico assisted the Santa Fe Public Schools Board of Education in enacting a resolution that limited the size of new elementary schools in the district.
