Singing her heart out at a concert Sunday wasn't the only thing Mexican singer Julieta Venegas did during her recent trip to Costa Rica – she also filmed a commercial to encourage kids to stay in school through the campaign “Engánchate al cole ” (“Get Hooked on School”), according to a statement from the U.N. Children's Fund (UNICEF).

“School is a place where you learn math, Spanish, biography and geography, but, most importantly, you learn to get along with others... Don't miss the opportunity; get hooked on school,” Venegas says in the commercial, filmed alongside Costa Rican students.

It will be strategically aired at the end of the school year to try to combat the dropout that usually occurs during this time. In Costa Rica, every year about 40,000 high school students abandon school for reasons including limited economic resources, poor performance, family problems and boredom, the statement said.

“We're sure Julieta Venegas' message will serve as an inspiration for the country to unite its efforts and achieve the national goal that no child or adolescent is left outside the classroom,” said Costa Rica's U.N. representative Seija Toro.

“Get Hooked on School” is part of efforts by the Public Education Ministry to keep kids in school, train teachers and improve the overall quality of secondary education in Costa Rica.
