Like last year, every public school across the Fredericksburg region earned full accreditation from the Virginia Department of Education with two exceptions, according to data released Wednesday.

Moss-Nuckols Elementary in Louisa County and Locust Grove Primary in Orange County received accreditation with warning because of scores on the new math Standards of Learning test.

Those two schools were among 39 of the state's 1,121 elementary schools to receive accreditation with warning for the 2012-13 school year.

Math SOL scores fell statewide because a more rigorous version of the test was implemented in the 2011-12 school year.

State accreditation ratings for this school year are based on student performance for the 2011-12 school year.

Only 43 percent of Moss-Nuckols students passed the math test last year. Locust Grove Primary students had a 68 percent pass rate, but still fell below the state benchmark of 70.

Students at those schools met the benchmark for the English, history and science SOL tests.

Locust Grove Primary received conditional accreditation the previous year because it was its first year of operation.

To achieve full accreditation, a school must meet the state's benchmark on the four SOL tests. High schools also must meet a standard for graduation.

Statewide, 93 percent of the state's 1,836 schools earned full accreditation for this school year.

That's a 3 percent drop over last year and 5 points lower than two years ago.

"This year's decrease in the percentage of schools meeting the fully accredited rating is attributed, in part, to results of the new college- and career-ready mathematics tests that were first introduced during 2011-2012," Superintendent of Public Instruction Patricia I. Wright said in a statement. "We can expect a similar impact next year when we see the results of schools implementing more rigorous standards and tests in English and science this school year."

Statewide, high schools showed improvement in their accreditation rate one year after the state implemented a new "graduation and completion index," geared at reducing dropout rates.

Ninety percent of public high schools earned full accreditation, a 4-point increase over results from the 2010-11 school year.
