The California Department of Education quietly released the 2012 Base Academic Performance Index statistics on Friday, and the Davis school district posted numbers that largely resemble the district’s ranking in recent years.
All of Davis’ traditional campuses earned an API over 800 points, the threshold for state recognition as a “high performing school.”
The Davis school district’s overall rating rose from 875 in the 2011 Base API to 880 in the 2012 Base API. Scores for individual schools are in the accompanying box.
Among the district’s small schools, Fairfield Elementary (two classrooms covering grades K-3) earned an API of 912. The Davis School for Independent Study (grades K-12) did not receive an API ranking in this round. King High School, a continuation program, had an API of 426.
In many cases, Davis schools posted 2012 base scores that were within five or 10 points of their 2011 base scores, although a few scores went up or down by as many as 20 to 25 points. The three junior high campuses were within 20 points of each other, and the high school program at Da Vinci Charter Academy and Davis High School were within a single point of each other.
All in all, the 2012 base figures reflect a degree of stability, with the district’s regular elementary, junior high and high school programs continuing to score over 800 for multiple years in a row.
Sorted by subgroup, the figures indicate that the district still has work to do in terms of closing the so-called achievement gap. The 2012 base API figures for Davis reflect African-American students as a group scoring at the same level as last year (764), with Latino students as a group posting a small increase (from 749 in 2011 to 759 in 2012).
Asian students as a group posted a 935 score (up five points from the previous year), white students posted a 908 score (up five points). Socioeconomically disadvantaged students scored 750 (up 10 points from the previous year), but the score for English learners showed a slight overall dip (from 753 in 2011 to 736 in 2012). Scores for students with disabilities rose from 637 in 2011 to 661 in 2012.
The base API, released in the spring, is the first installment in the annual API cycle. The other installment, the growth API, is released in the fall. According to the California Department of Education, “The base API starts the reporting cycle and is released approximately a year after testing. For example, the 2012 base is calculated from results of statewide testing in spring 2012 but is released in May 2013. The growth API, released after the base API, is calculated in exactly the same fashion and with the same indicators as the prior year base API but from assessment results of the following year.
“For example, the 2013 growth is calculated from results of statewide testing in spring 2013 and will be released in September 2013. In order to measure the academic improvement of a school, academic results in the form of the API are compared from year to year. Improvement (or change) in the API is the difference between the base API and growth API within a reporting cycle.”
