As of my last knowledge update in September 2021, I can provide you with a list of 20 U.S. states that have faced challenges and were often cited as having lower educational outcomes based on various indicators. Keep in mind that education rankings and assessments can change over time due to various factors, including policy changes and investments in education. Here are 20 states that have faced education challenges:
- New Mexico
- Louisiana
- Mississippi
- Oklahoma
- Alabama
- Arizona
- South Carolina
- West Virginia
- Nevada
- Alaska
- Arkansas
- Kentucky
- Tennessee
- Georgia
- Idaho
- Oregon
- Hawaii
- North Carolina
- Colorado
- Missouri
Please remember that this list is based on data and trends as of 2021, and the education landscape can evolve over time. States often implement reforms and initiatives to improve their education systems, so rankings and outcomes can change. For the most up-to-date information on the educational performance of U.S. states in 2023, I recommend consulting educational reports, research studies, and government agencies that regularly assess and report on education quality and outcomes.
