Nationally, scores also fell, with reading scores among the 1.5 million children taking the test falling one point to 502, math scores down three points to 515 and writing off three points to 494. The maximum score on any portion of the test is 800.
Chambersburg's scores also fell despite fewer students taking the test, down from 320 in 2006 to 292 in the past school year. An online SAT preparation program offered by the district also did not bear fruit this year.
"Obviously, that's something we're going to look at this year," Eric Michael, assistant superintendent for secondary services, said of the online program, which students could access in school or at home. About 170 students participated in the offering, but Michael said he did not have figures for how many completed the program.
"It should be concerning us as a nation," Michael said. There is a movement across the nation to make education more rigorous and "reinventing those high schools on a curriculum level to compete in the world market," he said.
Waynesboro Area Senior High School's scores fell from 2006 as well.
Juniors and seniors there averaged 502 in critical reading, 489 in math and 481 in writing. The scores were down about 13 points from the year before.
Changes in the test in recent years make it difficult to form comparisons, said Gloria Walker, assistant superintendent of the Waynesboro Area School District.
Scores traditionally fluctuate by class, she said.
"We do have a SAT prep course," Walker said. "We encourage all of our students to take the SAT even if they (just) want to think about college."
Mercersburg's James Buchanan High School had 180 SAT records from 2007, meaning about 65 more students took the test than the previous year. The school, which is in the Tuscarora School District, had scores from 310 to 730.
"A lot of juniors and seniors took the test," Tuscarora Superintendent Rebecca Erb said. "Whenever you look at the scores, the ranges are really huge."
Hoover attributed Greencastle's favorable scores to the district's dual enrollment program, college academy and graduation project class.
"We have made a concerted effort over the past years to raise our standards not only in what is required of our students, but in each individual class," he said. "I believe we are seeing the results of that effort."
