     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

anxietybased 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 farreaching 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.
