Best And Worst School Systems in America

The United States education system was affected tremendously by the coronavirus pandemic. Schools nationwide saw significant changes for the worse, between elevated levels of absenteeism, severe staffing shortages, school closures, and high rates of quarantine, which all led to many primary, secondary, and high school students falling behind. According to the latest National Assessment of Educational Progress, which regularly assesses student performance in different subjects, average reading test scores among 13-year-olds declined by 4 points on the NAEP’s long-term trends scale in the fall of the 2022-23 school year compared to the same semester in 2020. Average mathematics scores fell by 9 points in that same period — to the lowest in decades.

All assessments the NAEP has released in 2022 and 2023 show average scores have either declined or showed no improvement compared to previous assessments. Specifically, eighth-grade and 12th-grade reading and mathematics, and eighth-grade U.S. history and civics were lower compared to 2020. According to what Denise Forte, president and CEO of the nonprofit advocacy organization The Education Trust, told National Public Radio earlier this year, “Unfinished learning continues to weigh on students across all grades and subjects.”

There were also significant racial, ethnic, and gender disparities found in the test score data. For example, math scores fell by 13 points last fall among Black students compared to their white counterparts, representing the persistent, ongoing race and class disparities in the U.S. educational system. Girls’ math scores fell by more than boys’ compared to the 2020 assessment.

The foundation for academic success begins in primary and secondary school education, but states vary greatly in the quality of their education systems. 24/7 Wall St. developed an index of 10 factors measuring academic performance, resources, and equality to determine the states with the best and worst schools. Measures include factors such as student-teacher ratios, average Scholastic Aptitude test results used for college admissions, and the number of students who take Advanced Placement exams.

The median average SAT score among the 50 states is 1113, as per the College Board. While the average score in eight states — including high-population states Florida and Illinois — is less than 1000, it is above 1200 in 13 states, including Tennessee and Kentucky (No. 9 on the list). A perfect SAT score is 1600. (These are the states where students score the highest on the SAT.)

Student-teacher ratios above the median of about 15 students per teacher can be found in seven of the 10 most-populated states. Arizona (No. 46) has the highest ratio at nearly 24 students per teacher, while California has the second most crowded classrooms at 23 students per teacher. Vermont has the lowest ratio at about 11 students per teacher. Among the top 10 most-populated states, New York (No. 4) has the smallest average classroom size of between 12 and 13 students – though New York City’s ratio is about double the statewide average.

The average annual salary for elementary and secondary public school teachers ranges from $47,162 in Mississippi to $92,222 in New York. High school graduation rates start at 82% in Nevada up to nearly 92% in Connecticut. No data on graduation rates were available from Texas, Illinois, and Washington state. (Also see: the 50 best public high schools in America.)

Massachusetts is the state with the best school system and has the highest number of Advanced Placement exams, at 709 exams per 1,000 students, nearly double the median for all 50 states.

Here are the best and worst school systems in America.

Methodology

24/7 Wall St. developed an index of 10 factors measuring academic performance, resources, and equality to determine the states with the best and worst schools. The index consists of:

• The percentage of eighth graders who scored at or above proficient on the 2022 National Assessment of Educational Progress mathematics exam, from the National Center of Education Statistics.
• The percentage of eighth graders who scored at or above proficient on the 2022 National Assessment of Educational Progress reading exam, from the National Center of Education Statistics.
• The high school graduation rate for the 2019-2020 academic year, from the U.S. Department of Education.
• The high school graduation rate for economically disadvantaged students for the 2019-2020 academic year, from the U.S. Department of Education.
• The average SAT score among the class of 2022, from the College Board SAT Suite of Assessments.
• The difference between the average SAT score among the class of 2022 for students in the highest quintile of family income and the average SAT score among the class of 2022 for students in the lowest quintile of family income, calculated with data from the College Board SAT Suite of Assessments.
• The number of public high schools ranking among Niche’s 2023 Best Public High Schools in America list, adjusted for population, using data from the U.S. Census Bureau.
• The ratio of public elementary and secondary teachers to pupils in fall 2019, from the National Center of Education Statistics.
• Average annual pay for public elementary and secondary teachers in the 2021-2022 academic year as a percentage of average annual pay for all occupations, calculated using data from the U.S. Department of Education and Bureau of Labor Statistics’ Occupational Employment and Wage Statistics program.
• The number of AP Exams taken per 1,000 11th and 12th graders in 2021, from the College Board.
