Should struggling students be banned from clubs and sports?

Getting a bad grade in Rockingham, Vt. could get you kicked off the team! School officials there are considering new guidelines that would prevent students with bad grades from participating in extracurricular activities, such as sports and clubs. The proposal would affect students in eighth grade and below.

School board member Mike says the policy would motivate students to work harder in school. He drafted a letter to coaches, parents, and after-school program leaders to encourage them to allow only kids who are meeting certain academic standards into their program.

Not everyone gives such policy an A+. Some people argue that no student should be excluded from after-school activities. They say taking part in extracurricular activities can help kids do better in class by improving their participation and concentration skills. They say a 2009 study from the Centers for Disease Control and Prevention found that time spent in extracurricular physical activities does not take away from students’ ability to do well in the classroom . In fact, it may even help boost girls’ academic performance.

Students themselves have different opinions.

SCHOOL COMES FIRST

Why not require good grades to participate in those activities?

Kids need to understand that grades are important. School comes first, period. Getting good grades help you with life, help you go to college, get a job, and so on. Banning underachieving students from extracurricular activities not only gives them motivation to get their grades up, but allows more time to study or get help from a tutor.

DON’T BAN STUDENTS

Every student should be able to participate in extracurricular activities, no matter what his or her grades are. Extracurricular activities can help kids concentrate more on doing homework. They can help kids develop mentally and physically.

A school policy that tells kids with bad grades that they can’t be in sports or the school play is like judging a book by its cover. Every student is unique. A kid may have a learning disability, an attention issue, or a difficult time studying in his or her home environment. His or her teachers should find why the student is struggling. Together they should find out a solution that will keep the student in the activity.

73. What’s the author’s attitude to the policy that prevents students with bad grades from participating in extracurricular activities?

A. To indicate the author is against the policy.

A. Every kid is unique.

B. Extracurricular activities will benefit students mentally and physically.
