(WXIA) -- The Georgia Department of Education has created a 2014 Summer Reading Challenge for students in all grades.

The program was announced Thursday at Timber Ridge Elementary School in Cobb County. Its goal is to close the achievement gap that widens during the summer months, when children often don't read.

"No student should have to start the school year having fallen behind," State School Superintendent Dr. John Barge said. "That's what we know, and that's what we're committed to preventing, because that loss is preventable."

The challenge encourages students to read for at least 15 to 30 minutes every day. The GDOE outlined suggested summer goals for children based on their school years:

* K-2: 10 books
* 3-5: 8 chapter books
* 6-12: 5 fiction books and 5 nonfiction books

(WXIA) -- The Washington Post has unveiled its 2014 list of America's Most Challenging High Schools.

The newspaper determines the annual rankings through a ratio: the number of Advanced Placement, International Baccalaureate and Advanced International Certificate of Education tests a school gives each year, divided by the number of graduating seniors.

Thirteen Cobb County schools made the list, which features more than 2,000 high schools across the country. The listed numbers are each school's national ranking.

183. Walton HS
495. Lassiter HS
755. Harrison HS
936. Pope HS
1082. Campbell HS
1133. Wheeler HS
1184. North Cobb HS
1206. Kell HS
1334. Sprayberry HS
1474. Hillgrove HS
1523. Kennesaw Mountain HS
1718. McEachern HS
2001. Pebblebrook HS

Additionally, Marietta High School, which is part of a charter system, is No. 1058 on the list.

Educational practices and successes in Georgia were highlighted throughout the report.

"We have taken on some major initiatives and our success is a direct reflection of the collaborative efforts between our department, other education agencies and the hundreds of participating teachers, principals and district leaders around our state," Dr. Susan Andrews, Deputy Superintendent of Race to the Top Implementation in Georgia, said in a release.

"While educational reform work is never easy, we are pleased with the significant progress that our state has made as reflected in this report," Andrews added.

Some highlights from the report include:

* Nearly 300 Georgia teachers were placed in state public schools from alternative certification programs.
