The report card is in for Missouri schools, and five St. Charles County school districts passed with flying colors.

The state's Annual Performance Report (APR) rates the more than 400 school districts in Missouri serving students in kindergarten through 12th grade. The report is based on 14 standards related to academic achievement.

The academic performance areas include Missouri Assessment Program test results, attendance and graduation rates, college entrance scores and other indicators. Local school districts use the report as a tool to help identify strengths and weaknesses and to chart progress.

The Missouri Department of Elementary and Secondary Education released preliminary 2011 APR numbers on Thursday. The Fort Zumwalt, Francis Howell, Orchard Farm and Wentzville school districts met all 14 standards. The St. Charles School District met 13, but officials are confident that may change upon appeal.

"The same thing happened to us last year," said Randal Charles, superintendent of the St. Charles School District.

Charles said Thursday that the state wasn't giving the district credit for a subgroup that may change once the district responds to the initial APR findings.

State officials say the APR is part of the Missouri School Improvement Program, which began 20 years ago. The APR also is a major part of the state's accreditation process for schools. A K-12 school district has to meet at least nine of the 14 standards to be fully accredited, and at least six to be provisionally accredited. Meeting five standards or less can mean a school district is unaccredited by the state Board of Education.

Districts meeting at least 13 of the standards receive Distinction in Performance awards from the state. All five St. Charles County school districts have received this award since 2006.

The numbers released Thursday show 256 of the state's 447 K-12 school districts met all 14 standards, while 64 met at least 13. Last year, 229 of 448 districts met all 14. Some public school districts in Missouri offer only kindergarten through eighth grade; those districts have to meet different standards.

Some K-12 districts in the St. Louis region did not score as well, including the Warren County and Wright City districts, which met 10 standards, and Winfield, which met eight. Other St. Louis area districts that scored lower include Ferguson-Florissant, which met nine; University City, 7; Jennings, 6; and the city of St. Louis and Normandy, 4 each; and Riverview Gardens, 3.
