The Georgia Department of Education created the College & Career Ready Performance Index as a new accountability system to coincide with its receiving approval to waive the No Child Left Behind standards in February 2012.
The scores were released Tuesday and are designed to help parents and the public determine how well schools are performing.
Overall, Cobb’s elementary schools received a score of 85.4, based on a 100-point scale; middle schools, 87.1; and high schools, 86.3. Marietta City Schools got an 86.6 for its eight elementary schools, 83.6 for Marietta Sixth Grade Academy and Marietta Middle School and a 73 for Marietta High School.
Statewide results show elementary schools averaging an overall score of 83.4; middle, 81.4; and high, 72.6.
“While pleased with our scores, we still have work to do,” said Cobb Schools Chief Academic Officer Amy Krause.
She and her team are still analyzing the results.
Cobb Superintendent Michael Hinojosa said he too was happy with the initial results and believes it validates the hard work going on in his school system.
“Many of our schools, particularly our high schools, are performing at very high levels,” he said. “Clearly, there are also areas where we can show improvement, and intend to develop strategies to address those areas.”
Eleven of Cobb Schools’ 112 schools performed below a 70 on the scale.
These are Riverside, Compton, LaBelle, Green Acres, Birney, Norton Park, Hollydale and Sanders elementary schools and Pebblebrook, South Cobb and Osborne high schools.
The three lowest performing schools in Cobb were Riverside Elementary with a 59.4 and Compton and Sanders elementary schools, both with 61.1.
The three highest performing schools in Cobb were Hightower Trail Middle School with a 99.5; Mount Bethel Elementary School, 99.3; and Dickerson Middle School, 99.2.
There were 50 schools in all that scored 90 or above; 26 between and 80 and 89.9; and 25 between 70 and 79.9.
Scores for Marietta
All of Marietta City’s 11 schools received a 70 or higher.
The school with the highest score was Marietta Center for Advanced Academics with a 102.7, and the lowest was Marietta High with a 73.
Marietta High Principal Leigh Colburn said the numbers for her school fell about where she thought they would.
“I don’t know of a school that is more representative of the totality of this state … demographically, socioeconomically and racially,” she said. “While we have high performing kids, we also have kids who are struggling to graduate.”
She was pleased to see that Marietta High’s scores were higher than the state and fell in line with other metro Atlanta high schools as well.
As far as improving upon these first scores, Colburn said she believes Marietta High School is in a good position to build on its success because it is a smaller district.
“We can quickly and strategically respond, unlike larger districts,” she said.
She urged parents to study the data and speak to principals about where their scores stand, what the school’s goals are and what strengths and challenges they have to build on.
“This new instrument allows them to see multiple nuances of the school,” she said, adding that it is a better tool than data produced under Adequate Yearly Progress with No Child Left Behind.
Marietta Associate Superintendent Dayton Hibbs said they will be sending a letter to parents to give information about each schools’ scores and an overview of the highlights.
The scores for the rest of the elementary schools in Marietta were as follows: Park Street, 78; West Side, 91; Lockheed, 77.6; Sawyer Road, 86.4; Dunleith, 86.6; Hickory Hills, 74.1 and Burruss, 87.4. Marietta Sixth Grade Academy received an 89.1 and Marietta Middle a 79.6.
Breakdown of the scores
Schools are graded on a 100-point scale, and scores are made up of three major areas: achievement, 70 points; progress, 15 points; and achievement gap, 15 points.
Schools can also receive up to 10 “Challenge Points” if it has a significant number of economically disadvantaged students, English language learners or students with disabilities meet expectations.
They can also receive points for performing better than the targets outlined in the index.
