PORT ALLEN - West Baton Rouge Parish School Superintendent David Corona on Wednesday said parish schools are outpacing the state in raising achievement among the poorest-performing students.

The school system, however, is lagging behind the state in getting students into the top two levels of achievement, he said.

Of the 28 tests taken by students in third through 11th grades, students are ranked into the following categories in descending order: mastery, advanced, basic, approaching basic and unsatisfactory.

Students are graded in math, science, social studies and English language arts.

In his brief rundown of student performance for the 2010-11 school year, Corona said West Baton Rouge students outpaced state averages in raising student performance out of the unsatisfactory ranking in 23 of 28 tests taken.

Parish students, however, ranked higher than the state at the mastery and advanced levels in only four of 28 tests, he said.

“We know how to get kids over the hump, we’re just not getting them into the upper echelons of achievement,” he said.

Corona, at the School Board’s regular meeting, called for a renewed focus to get more students into the top two levels going forward.

The school system has and will continue to put measures in place, including hiring interventionists, to aid students in areas where they struggle, he said.
