Boston magazine just released its annual ranking of the “Best Public High Schools in Boston 2018,” which takes a look at “public high schools in towns or districts within, or partially within, I-495.”

At the top of the list is Dover-Sherborn Regional High School, which boasts an enrollment of 665 students and a graduation rate of 99.4 percent.

The school also picked up high marks for MCAS exam scores, with 100, 99, and 99 percent of 10th grade students scoring proficient or higher on reading, math, and science, respectively. Students also averaged scores of 640 for reading/writing and 645 for math on the SAT, according to the ranking.

The magazine used data for each of the 150 schools from the Massachusetts Department of Elementary and Secondary Education. Charter schools and “highly specialized schools” as well as schools “reporting insufficient information” were omitted, according to the publication.

Smaller class size and a lower student-to-teacher ratio were also favored. (Dover-Sherborn High averaged classes of 15.7 students and a 11.5 ratio.)

“To calculate the rankings, statistician George Recck, director of the Math Resource Center at Babson College, analyzed the results, comparing each high school’s data points to the overall average for all schools,” the magazine wrote. “He then applied a percentage weight to the standardized value for each school to create an aggregate ‘score’ to determine each high school’s rank.”

This year’s list didn’t see a first-place shake-up. Dover-Sherborn has taken top honors on the list, either as the No. 1 public high school or as the best school district, in every Boston ranking since at least 2013.

5. Manchester Essex Regional High School

6. Newton South High School
