     The Guidance Department (教导处) at Berryville High School has a staff 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 Freman, 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 these want to

talk about the schedules. 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 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.
