Summer is almost here, which means it is time to sign(报名) your children up for swim cl

asses again at the Community Pool. Classes begin on Monday, May 1, and will continue throughout the summer. Fifteen swim classes are being offered. Each class lasts ten hours. A new class starts each week of the summer. Each class costs $20. The pool is big enough for six students per class.

Classes will increase in difficulty each week. The first week is for children up to six years old. The last week is for advanced swimmers who want to improve their race and endurance skills.

Students can sign up for as many classes as they like, but they must pass the skills level test. For example, students who sign up for Level 4 (Stroke Readiness) must show their certificate(证书) for completing Level 3 or must demonstrate the front crawl and backstroke. Children cannot sign up for a level they are not ready for. Children who have never attended Community Pool classes must show up April 29 or 30 for a swim skills evaluation(评估). Instructors will rate the students and assign them to a particular skill level.

Swim classes are fun for all. Children learn new skills and make new friends. Parents get to meet other parents in the community. Swimming, like bicycling, is a healthy and valuable skill that, once learned, is never forgotten.

“It's a joy to teach young children,” said Ginger, the lead instructor for swimming programs. “More than half of them are terrified when we put them into the water the first time. Two months later, they're begging their parents to go to the pool every day.”
