DC public schools are planning to test students on their knowledge of human sexuality, contraception and drug use this spring.

According to the Office of the State Superintendent of Education, the exam will be the first standardized test on health and sex education in the country. The 50-question exam will be given to students in grades 5, 8 and 10.

The city’s rates of childhood obesity, sexually transmitted diseases and teen pregnancy are among the highest in the country. School officials say the test will help determine what students know about risky behavior.
