The U.S. Department of Education requires colleges to disclose a variety of information for any financial aid eligible program that “prepares students for gainful employment in a recognized occupation”.
The information provided in each document includes the certificate program's length, completion rates, costs, the percentage of students who take out loans, and when available, employment rates.
The employment rates included in these documents are based on data provided by the California Community College Chancellor's Office through it's Doing What Matters initative.
The employment rate is calculated by taking the number of students who took one or more credit courses in a particular program during the 2013-2014 academic year and were employed within six months of leaving the college.
As noted by the CCCCO:
"Employment and earnings metrics are based on records in California’s Employment Development Department’s Unemployment Insurance data. Unemployment Insurance data only contain wages for those employed in an occupation or industry covered by Unemployment Insurance in California. This excludes individuals employed by the military or federal government, and those who are self‐employed, employed out of state, unemployed, or not in the workforce after completion of an award. The Unemployment Insurance data do not indicate how many hours an individual worked, or part time/full time status or employment in field of study. Data is only matched for students with a valid Social Security number".
More information about employment data is available here.
More information about these programs can be found on the college's CTE homepage.
