All visitors are required to sign in upon entering the building.  All visitors are also required to wear school provided identification.  Visitors parking on the school lots need to sign in so their cars will not be subject to parking enforcement.

Students who wish to bring a guest must make arrangements with a BHS administrator at least one week in advance.  In general, permission to visit will be granted only to student guests residing outside Bloomington‑Normal.

Visitor's privileges may be revoked or suspended at any time.  Fridays and days immediately before and after any vacation period and/or closing days of school are considered to be inappropriate times for visitors.

State law provides that "teachers and other employees may request any person entering a public school building to identify himself and the purpose of his entry.  A person who refuses to provide such information is guilty of a Class A misdemeanor.  (Section 24‑25 of the School Code of Illinois).
