     Every day,all across the nation,as many as one in four children refuses to go to school.The reasons

are various."School Refusal",formerly known as"School Phobia",is an actual anxietybased disorder.

Many children are vague about their complaints and unable to be sure what is making them anxious,so

it is sometimes regarded as typical childhood will fullness.However,the effects of constant school refusal

can be farreaching for your child's education.

     So,where's the line between what's normal and what's not?"You need to look at whether it is affecting

the child or family's normal life,"explains Christopher Kearney,Ph.D.In other words,if a child's grades are

suffering from frequent absences or a parent's job is disturbed,it is time to look closely at the issue.

Parents should listen carefully to children who say they can't go to school because of "untestable things"

such as stomachaches or headaches.While these complaints alone don't necessarily indicate school

refusal,there may be deeper problems if combined with general complaints about school,talks of threats

at school and so on.

     There are different kinds of behavior in school refusal.Some children are influenced by their friends

who skip school to hang out with their friends,showing a sense of rebellion(叛逆). Some children cling to

their mothers,screaming at the thought of having to enter the school building.

     However,that doesn't mean that getting a child back into the classroom is impossible.According to

Maryann Roth,a school psychologist and guidance counselor(顾问),parents should attempt to make the

child get back to school,no matter how hard it is.Working closely with school officials and possibly a

specialist to create a plan is a necessary step.
