Definitions: This indicator includes the 4-year Adjusted Cohort Dropout Rate, reflecting students who entered the 9th grade and did not receive a high school diploma within 4 years.

Data Source: California Department of Education, Education Demographics Unit, Cohort Outcome Data - List of Counties   (Sacramento, CA: California Department of Education) (Accessed July 1, 2015). Counties with fewer than 10 cases are not reported.

Footnotes: 4-year Adjusted Cohort Dropout Rate - This is the rate of students that leave the 9-12 instructional system without a high school diploma, GED, or special education certificate of completion and do not remain enrolled after the end of the 4th year. The formula is similar to the formula listed in 1.2, but the numerator is replaced with the number of students in the 4-year cohort that dropped out by the end of year 4 of the cohort. Low Number Event (LNE): Data not reported when fewer than 10 cases exist or when applicable % is based on fewer than 10 observations.
Asterisks* An asterisk indicates that data should be interpreted with caution. Asterisks were used to note low number of events (fewer than 10) or unstable data with large confidence intervals. Data or estimates with low numbers and large confidence intervals indicate that a data point may not be a true representation of the larger population. NA (Not Available) Data that are not available are noted as NA. The most frequent reasons for using the NA annotation include the unavailability of longitudinal data, data suppression from the original data source due to a low number event, or statistically unstable estimates.
