The California Department of Education has released the 2010 Academic Performance Index (API) Base Reports.

The reports include the Base APIs, Growth Targets, and Statewide and Similar Schools rankings for nearly every public school and district as mandated by California’s Public Schools Accountability Act.  The 2010 Base Reports reflect results of 2010 statewide testing.

Of the 182 Ventura County API recipient schools that had sufficiently accurate data, 97 (53%) schools posted APIs of 800 or better, down slightly from 55% last year.   Vista Fundamental Elementary School in Simi Valley Unified School District attained the highest base API in Ventura County, moving up three points to 955 on the 1000-point scale.   For the third year in a row, the highest API  for a middle school in 2010 was 925, earned by Medea Creek Middle School in Oak Park Unified School District.  This reflects a twenty-two point API gain for  Medea Creek. Finally, the highest base API for a high school was 907, earned by Oak Park High School in the Oak Park Unified School District.

Moorpark Community High School achieved a 108-point gain, the greatest increase in a school’s current Base API.  Not far behind them is Sierra High School in the Fillmore School District with an 88-point gain, and Christa McAuliffe Elementary School with a 77-point gain.

To continue to look at outstanding performers, we must search out those schools that score well in an absolute sense (statewide rank) and in relation to schools with similar student populations (similar schools rank). This year three Ventura County Schools received both a Statewide Rank of 10 and a Similar Schools Rank of 10:

• Brookside Elementary (Oak Park Unified)

• Oak Park High School  (Oak Park Unified)

Seventeen schools in Ventura County (9%) scored in the top 10% of California schools.  Districts represented include:  Conejo Valley Unified, Oak Park Unified, Pleasant Valley Elementary, Santa Clara Elementary, Simi Valley Unified, and Ventura Unified.

Twenty-six schools in Ventura County scored in decile 9, meaning that 24% of schools in Ventura County are currently ranked in the top 20% of the State.

Ninety-nine schools (54%) ranked above average (deciles 6-10).

Often school success is in large part a product of district-wide efforts.  This can be seen in a number of local schools that, while facing some of the region’s most formidable educational challenges, have made more academic progress than similarly challenged schools.  Forty-two percent of the eligible schools earned Similar School Ranks in the top half (deciles 6-10).  Eight schools scored in the top ten percent (rank of 10) of their California peers on this similar school ranking.

Since 2002, school districts have received API scores.  Ten school districts posted district-wide scores at or above the State target of 800, two more than in 2009. Districts included Santa Clara Elementary (938), Oak Park Unified (916), Conejo Valley Unified (867), Pleasant Valley Elementary (863), Mesa Union (854), Moorpark Unified (836), Simi Valley Unified (816) and Ojai Unified (814), Mupu Elementary (801), and Ventura Unified (800).

Mr. Mantooth stressed that, “I am confident that the staff, students, and parents of our Ventura County schools will continue their efforts to help all  students succeed.  Even with these very challenging economic times, they are working to narrow the achievement gaps between traditionally higher and lower- scoring student subgroups.  The focus has not wavered from having every student college and career ready.  Their efforts have the full support of local school districts and boards of education.  It takes everyone involved in our student’s education to keep our schools on the path toward academic excellence.”


The Academic Performance Index (API) is a numeric index (or scale) ranging from a low of 200 to a high of 1000 that reflects the academic performance level of a school or district (LEA) based on the results of statewide testing.  The 2010 Base API reports reflect results of 2010 statewide testing.  The results of a number of newly developed statewide tests that more accurately assess the performance of students with disabilities have been included in the calculations of the 2010 Base API. Calculations for the 2010 Base API scores include:

• California Standards Tests (CST) in English-Language Arts and Mathematics in grades 2 through 11 including writing assessments in grades 4 and 7.

• The CSTs in Science in grades 5 and 8 through 11.

• The CSTs in History-Social Science in grades 8, 10, and 11.

• The California Modified Assessment (CMA) in English-Language Arts in grades 3 through 9.  The CMA is an assessment of California content standards based on modified achievement standards.  It is offered to some students with disabilities in accordance with their individualized education program.

• The CMAs in Mathematics in grades 3 through 7.

• The CMA in Science in grade 8.

• The CMA in Algebra 1 in grades 7 through 11.

• The CMA in Life Sciences in grade 10.

• The California Alternate Performance Assessment (CAPA) in English-

Language Arts and Mathematics in grades 2 through 11.  The CAPA is an alternative assessment for students with the most significant cognitive disabilities who are unable to take the CSTs or CMAs.

• The CAPA in Science in grades 5, 8, and 10.

• The California High School Exit Examination (CAHSEE) results in English-Language Arts and Mathematics for grades 10 through 12.

The State Board of Education has set 800 as the target API that schools and districts should strive to attain.  Additionally, each school is rated on two 10-point scales, one reflecting the school’s overall level of achievement (for example, a 10 would indicate the school is in the top 10% of all California schools), and the other representing how well the school has performed as compared to schools with similar student populations elsewhere in the state.

Schools with numerically significant groups of students within schools also have annual APIs and annual growth targets.  Over the years the API subgroup targets have become more challenging.  Schools must make a minimum of 5% growth between its 2006 subgroup APIs and 800 until the API score approaches the state target of 800.
