美国学校经常发告示，这是我刚刚收到的一个。总而言之，家长想去学校转转，不能随便推开门到处逛。

Parent Visitation Guidelines
            The Howard County Public School System welcomes visitors to our schools. Visitors to a school campus, building or classroom should follow these procedures in order to limit interruptions and distractions to teaching and learning and maximize safety for all.

Contact the Principal to discuss the purpose of the visit and to establish a convenient time for both the visitor and the school. The school will arrange for an escort for the visitor.

Sign in at the main office and receive a visitor badge. Visitors may be required to provide a photo ID.Schedule any desired follow-up meetings with school staff at a mutually convenient time.

To avoid interrupting instruction, students may not shadow other students.

Interactions between visitors and school staff or students will be limited.

In some cases, the desired information may be more conveniently obtained through one of the following sources:
School system website (www.hcpss.org), individual school websites, HCPSS News, on-line school profiles, or archived school newsletters
School Locator, for the school attendance area of a specific address

School counselors and administrators, via phone or email
A school visit during American Education Week, Nov. 12-16
