    The Guidance Department (教导处) at Berryville High School has a staff (员工) of eleven teachers.

Most of their work is done with the students. But the staff sees a lot of parents, too.

    "parents meetings make clear monthly diagram (图表)," says Mildred Foreman, head of the Guidance.

"This diagram stays much the same from year to year. The busy months are October, March and May."

     September, the beginning of a new school year, starts rather slowly. Few parents come in. Most of

them want to talk about the schedules (日程安排). October brings many problems caused by some

students. Some parents are called in. Others come by themselves. Things quiet down in November.

December is a quiet month. "It's the holiday," Ms Foreman says. "people want to come in, I know, but

they decide to wait until after New Year's Day."

     Report cards go home just before Christmas holidays. Bad marks (分数) bring parents in as school

opens again. This happens again in March, another report card month. May is always the year's busiest

month. That's when parents begin to think that their children may be asked to stay in the same grade again.

They come in to see if anything can be done before things are decided in June.
