How did US News & World Report come up with rankings?

U.S. News & World Report ranked high schools across the United States based on the following six factors:

  • College readiness
  • State assessment proficiency
  • State assessment performance
  • Underserved student performance
  • College curriculum breadth
  • Graduation rate

“Using this methodology, schools earned an overall percentile score between 0 and 100 at two decimal places,” the site said.

U.S. News drew on data on Advanced Placement and International Baccalaureate exams from the College Board and International Baccalaureate.

Individual states provided state assessment data and graduation rates, while other data came from the U.S. Department of Education Common Core of Data.

U.S. News & World Report said it works with RTI International, a nonprofit social science research firm, to assess and rank public high schools across the country, and produce rankings of charter schools and magnet schools.

How did SLO County high schools compare?

The study compared graduation rates, college readiness, enrollment and student-to-teacher ratios at all of San Luis Obispo County’s public schools.

Both Coast Union in Cambria and Central Coast New Tech in Nipomo reported perfect 100% graduation rates, followed by Templeton (98%), San Luis Obispo and Nipomo (97%), Morro Bay and Arroyo Grande (96%), Atascadero (93%) and Paso Robles (91%).

Students at Coast Union were also the most prepared for college, with a readiness score of 50.5, according to the rankings. The college readiness score was based upon the number of 12th-grade students who took and passed at least one AP exam.

San Luis Obispo ranked next with a score of 46.7, followed by Arroyo Grande (38.1), Templeton (34.4), Morro Bay (22.3), Nipomo (22), Paso Robles (21.3) and Atascadero (19.4).

Central Coast New Tech did not have a listed college readiness score because the school itself does not offer AP classes.

The rankings also took into consideration student-to-teacher ratios.

Coast Union, with a total enrollment of 149, had by far the smallest ratio, with nine students to every one teacher. The next smallest school, Central Coast New Tech (267 students) had a student-to-teacher ratio of 17-to-1, followed by Morro Bay (18-1), Nipomo and Atascadero (19-1), Arroyo Grande (20-1), San Luis Obispo and Templeton (21-1) and Paso Robles (22-1).

Beside these factors, the U.S. News rankings also considered students’ math, reading and science proficiency.
