Overview
• New in 2011 Base API• New Components• Options• Methodology• Some Results
3
New in 2011 Base API• All CMA scores will count
– Grade 10 & 11 ELA and Geometry– May impact SCFs, especially high school
• Some ASAM and Alternative Education scores will revert to the student’s school of residence
• Continuous enrollment means no enrollment gap exceeding 30 calendar days (CALPADS)
• Graduation Rate• Grade 8 and 9 Dropout Rate
4
Disclaimer
• Graduation and Dropout proposed changes– Presented by the CDE Technical Design Group– Being reviewed by PSAA Advisory Committee– Some rules will likely change– Final options to State Board of Education in May– Actual Base API out in May/June
5
New Components• Graduation Rate
– Schools/LEAs with a Grade 12– Same targets and calculations as AYP– Class of 2010 4-year cohort rate
• School level only – no subgroups
– 5 and 6 year Graduation rate in the near future• Relative weights defined in Ed Code
6
New Components (cont.)
• Grade 8 and 9 Dropouts– Grade 9 if highest grade in school is grade 9 (69)– Academic year dropout
• Dropouts during academic year
– Transition dropout• Finished grade, did not show in next grade in a
California school (CALPADS matching on SSID)• Accountability at LEA and State level only
7
New Components (cont.)
• Grade 8 and 9 Dropouts (cont.)– Target is 1%
• Statewide for 2008-2009 – 1.28%• 72% of schools less than 1%• 2392 Schools in 2008-2009
– 2008-2009 data• 2010 Base API on Dataquest
8
Options
• Technical Design Group– Option 1
• Add two content areas to current calculation– Graduation Rate (weight = .33)– Dropout Rate (weight = .21)– Each represents 10% statewide content area weight– Rejected by PSAA Advisory Committee
9
Options (cont.)– Option 2
• Assessment API sub-index (current API)• Graduation Rate sub-index
– Given a value between 200 and 1000– 90% corresponds to a score of 800– School or LEA level only (no subgroups)
• Dropout Rate sub-index– Given a value between 200 and 1000– 1% corresponds to a score of 800– School or LEA level only (no subgroups)
• Composite API index– Weighted average of the above three– School or LEA level only (no subgroups)
10
Graduation Sub-Index• Values above/below
90%– Conversion table– Option A
• “Conversion without Floor”
• 0% = 200 points• Linear assignment
between 0% and 90%• 90-100%, linear between
800 and 1000

Weights• PSAA requires Assessments to be at least 60%• Actual weights yet to be determined• Examples:
Sub-Indexes Example 1 Example 2 Example 3
Assessment Sub-Index 0.60 0.80 0.90
Graduation Rate Sub-Index 0.30 0.15 0.05
Dropout Rate Sub-Index 0.10 0.05 0.05
20
Impact
• Depends on the district– Higher API schools often have higher graduation
rate and lower dropouts– Lower API schools will likely be more negatively
impacted.
• Depends on the weights
21
Likely Options
• Graduation– PSAA Advisory Committee focusing on Option A
(no floor).– Revised cut points
• Linear from 70% to 100% instead of 90% to 100%• More beneficial to lower scoring schools/LEAs

Conclusions
• 2011 Base API to have Graduation and Dropout Components
• Impact will vary depending on weights– Higher API sub-index weight – closer to current
API
• Follow May SBE meeting for final rules• Impact of new Continuous Enrollment rules• ASAM/Alternative scores reassignment
