According to the districts, Cobb’s composite score was 22.2 and Marietta’s was 21.0, compared to the state average of 20.7 and the national average of 21.1.
The ACT is a curriculum-based achievement test designed to measure college readiness and preparation. The ACT includes exams in English, reading, math and science and an optional writing portion. Scoring on the exam is based on a scale of zero to 36.
In Cobb, 3,571 students, or 322 more than in 2011, took the ACT as juniors or seniors last school year, and for the first time in seven years students did not post a higher composite score than the year before, dropping 0.2 points from 2011’s 22.4.
Ten of Cobb’s 16 high schools posted average composite scores higher than the state and national averages, and the district as a whole scored higher than the state and national averages in all four testing areas.
“The performance on the ACT clearly shows our students are well-prepared for college-level work and can compete with students from anywhere in the country,” Cobb Superintendent Dr. Michael Hinojosa said. “I am also pleased to see the increase in performance in student groups. One of our strategic goals is to
narrow the achievement gap among students groups, and the ACT results show four of our six groups with higher composite scores. That’s a clear indicator we are making progress.”
Lassiter and Pope tied for the highest composite score in the Cobb district with 24.6, but Walton, a charter school, posted a 25.6. The school with the lowest composite score is Osborne High in central Cobb with 16.7.
2012 scores reported for the 181 Marietta High seniors who took the ACT, up from 173 in 2011, were higher than the state averages in three of four test areas: English, 20.5; math, 20.9; and science, 21.0. The overall composite score for Marietta High, 21.0, is 0.5 points lower than 2011.
Fifty-two percent of Georgia’s 2012 graduating seniors, or 47,169 students, took the ACT with an average composite score of 20.7. This average is up 0.1 points from last year’s 20.6 and 0.4 points less than the national average of 21.1.
The state report also revealed that more of Georgia’s students, 10,377 in 2012 compared to 9,015 in 2011, demonstrated college and career readiness this year in all four test areas. Locally, 31 percent demonstrated college-readiness in Cobb and 24 percent in Marietta.
Marietta Superintendent Dr. Emily Lembeck said Marietta High’s college-readiness benchmarks are up 1 percentage point from 2011.
“When compared to the state percentages, Marietta’s ACT college readiness benchmark scores were higher in all areas, and more students also elected to take the ACT in addition to or instead of the SAT,” she said.
The ACT College Readiness Benchmarks are based on grades earned by students in college, define college and career readiness, and report student performance results relative to that goal.
The ACT college readiness benchmark scores help determine whether students are likely to be successful in core college courses such as English Composition, Algebra, Social Science, and Biology.
Students scoring at least 18 on the English test, 22 on the algebra test, 21 on the social science test and 24 on the biology test have a 50 percent chance of obtaining a B or higher in the corresponding credit-bearing college courses.
