Nearly Half of Blacks, Latinos Drop Out, School Study Shows

In the Los Angeles Unified School District, the situation was even worse, with just 39% of Latinos and 47% of African Americans graduating, compared with 67% of whites and 77% of Asians.

The report concluded that the public remains largely unaware of the true extent of the problem because the state uses "misleading and inaccurate" methods to report dropout and graduation rates.

The California Department of Education reported that 87% of students graduated in 2002, but researchers pegged the rate at just 71%. Nationally, about 68% of students graduate on time, according to the analysis.

The troubling graduation rates are most alarming in minority communities, where students are more likely to attend what researchers call "dropout factories."

The exodus of tens of thousands of students before 12th grade is exacting significant social and economic costs through higher unemployment, increased crime and billions of dollars in lost revenue, according to the report by researchers from Harvard, Johns Hopkins, UCLA and UC Santa Barbara, among others.

"A diploma is a passport to economic success. If our high schools can't get students the education they need, that will be

Statewide, just 57% of African Americans and 60% of Latinos graduated in 2002, compared with 78% of whites and 84% of Asians, the report said.

Using enrollment data, researchers produced what they believe are the most definitive graduation rates for California and its largest school systems.

They cast aside the state's method, which even California Education Department officials acknowledge is flawed. The state officials say they are forced by the federal government to use a formula that relies on undependable dropout data from schools.

The Harvard report found that African Americans and Latinos in the state were far less likely to graduate than their white and Asian peers, reflecting an achievement gap that first appears in elementary schools.

UCLA researchers noticed one troubling pattern in Los Angeles Unified: Most students who leave high school do so between ninth and 10th grades.

In several Los Angeles high schools, UCLA researcher Julie Mendoza found that less than one-third of ninth-graders graduated on time.
