Only in writing did the Westport sophomores' scores fall. About 92 percent hit the goal mark, whereas almost 97 percent reached the goal in 2010.

Westport students outperformed the state averages in each of the four tested areas by huge margins.

In math, for example, only about 50 percent of students in Connecticut hit the goal level. In reading, about 45 percent of students statewide met or exceeded the goal.

Compared to their peers in Fairfield, Westport students posted better scores in each category, by a margin of at least seven percentage points. The difference between Westport pupils' scores and those of their peers in Norwalk was even more marked.

Only 35 percent of that city's 10-graders reached the goal level in math, while 40 percent met or exceeded the goal in reading.

Neither Superintendent of Schools Elliott Landon nor any representatives from his office could be reached for comment on the CAPT results by press time.

Town students also ranked as high performers, when scored for proficiency on the CAPT. A less stringent benchmark than the "goal" level, the "proficient" standard is used to determine how many schools are meeting the targets of the federal No Child Left Behind law.

In math, 97 percent of Westport students were at or above the proficiency level; in science, 98 percent were proficient; in reading, close to 100 percent were proficient; and in writing, 99 percent were proficient.

Compared to Westport, students in Connecticut scored on average proficiency at least 10 percentage points lower in each of the four tested areas on the mandated statewide exams.
