(March 21, 2006) -- LBReport.com posts a link below to CA Dept. of Education's Academic Performance Index (API) rankings, released March 21, allowing readers to compare the academic performance of all LBUSD schools against schools statewide...and in detail concerning each school.
Today's rankings apply API base scores to reflect "deciles" (percentiles of ten), ranking each school within a 10% academic performance level chunk with 10 as the best (the top 10%) and 1 as worst (the bottom 10%).
As in previous years, several LB elementary school are in decile 10 (top 10% = Gant, Fremont, Lowell, Naples) and 9 (top 20% but not top 10% = Longfellow, Newcomb, Twain).
Among LB Middle Schools, Hughes and Stanford scored in decile 9. Franklin and Demille scored in decile 1.
As in past years, with the exception of LBUSD's Academy of Math & Science (a magnet school, achieving decile 10), the highest ranking LB High Schools reached decile 7 statewide (within top 40% but not top 30% = Lakewood, Poly, Wilson, Savannah [grade 9]); ELB's Millikan High is in decile 5...and Jordan and Cabrillo are in decile 2 (bottom 20% but not lowest 10% = Jordan).
In addition to statewide ranks, the CA Dept. of Education also releases deciles comparing each school to what it calls "similar" schools" using what CDE calls "similar demographic characteristics." These include "Pupil mobility, Pupil ethnicity, Pupil socioeconomic status, Percentage of teachers who are fully credentialed, Percentage of teachers who hold emergency credentials, Percentage of pupils who are English learners, Average class size per grade level, Whether the schools operate multitrack year-round educational programs." Since Jan. 2006, the demographic characteristics also include "Grade span enrollments (grades two, six, seven to eight, and nine to eleven), Students in Gifted and Talented Education program, Students with disabilities, Reclassified fluent-English-proficient (RFEP) students, Migrant education students, Students in full-day reduced class size program."
In some cases, the "similar school" comparison produces higher deciles. Cesar Chavez Elementary (just NW of LB Civic Center) is in decile 3 statewide...but decile 8 compared to schools with similar demographic characteristics.
However some LB schools that ranked well compared to schools "statewide" scored lower when compared to demographically "similar schools." ELB's Gant Elementary was in decile 10 statewide...but only decile 7 when compared to demographically similar schools. ELB's Prisk & Cubberley Elementary schools were in decile 8 statewide but only decile 4 compared to demographically similar schools.
ELB's Millikan High, in decile 5 statewide, was in decile 3 compared to demographically similar schools. NLB's Jordan High, in decile 2 statewide, was also in decile 2 compared to demographically similar schools.
