Here's a Brief Summary:
School Zone: The GFSZA defines “school zone” as: 1) in, or on the grounds of, a public, parochial or private school; or 2) within a distance of 1,000 feet from the grounds of a public, parochial or private school.
========================
The federal prohibition against possessing a gun in a school zone
does not apply, however:
>To people licensed by the state or locality to possess the gun. This exception applies to many people licensed to possess firearms or to carry concealed firearms; see our summaries on Licensing Gun Owners or Purchasers and Carrying Concealed Weapons for more information about these licensing requirements.
>If the firearm is unloaded and “in a locked container, or a locked firearms rack that is on a motor vehicle.”
>If the firearm is possessed for use in a program approved by a school, or in accordance with a contract entered into between a school and the individual or an employer of the individual.

State law summaries are also included on that website. It's worth a visit there for a refresher. [Yeah. I know. They present the Worst Case in the Worst Light. Which is informative. And what they say clinches the argument for holding a concealed carry license.]
