As statewide high school exit exam results dipped slightly, results from Lodi and Galt schools remained about the same.
Seniors passed California's high school exit exam at a slightly lower rate than in the previous year, as the test was widely administered to special education students for the first time.
The state Department of Education said about 90 percent of the graduating class of 2008 had passed the test by May. The previous year, 94 percent passed the two-part test of math and English by the same time.
In Lodi, where district officials have spent a great deal of time and money trying to overcome an "achievement gap" between white and minority students, Hispanic and black students still lagged behind their white counterparts.
Only 61 percent of Hispanic students and 63 percent of black students passed the English part of the test, while 69 percent of Hispanics students and 57 percent of the black students passed the math section.
White students in Lodi did much better, with 89 percent passing the math section and 89 percent passing English.
Galt students performed at a level similar to past years, with about 80 percent of students in the 10th grade passing.
Most Hispanic students in the district tested well, with 72 percent passing the English section and 73 percent passing the math part. Of the district's white students, 89 percent passed the math section and 90 percent passed the English part.
Lodi Unified's Superintendent Cathy Nichols-Washer was out of the office Tuesday afternoon and unavailable for comment.
Statewide about 54 percent of blind, deaf and other disabled students who are classified as special education students passed the exam.
Of Galt's 48 special education students in the 10th grade who took the test, 16 passed the English section and 13 passed the math.
Locally, 29 percent, or 57 students, in the 10th grade in Lodi Unified's special education program passed the English part and 35 percent, or 67 students, passed English.
The exam became a condition for graduation in California starting with the class of 2006. Students have multiple chances to take the test, starting in 10th grade.
Students who don't pass in time to graduate with their class can take remedial courses or enroll at community college and try again.
