Seneca Valley School Board is expected to finalize several policy changes Monday, including one covering such electronic devices as cell phones.

The revision includes a list of specific devices that are banned or must be turned off at school. A provision that would have banned cell phones has been modified so they are permitted but must be turned off, be set on vibrate or silent.

Under the policy, laser pointers and pagers or beepers will be banned from school and school buses. Devices such as radios, Walkmans, CDs, iPods, MP3 players and handheld games will be allowed on school buses as long as they are used with earphones and don't cause a disruption.

Building administrators can make exceptions to the policy for health and safety reasons and instruction-related activities.

The board is also updating its drug-testing policy so that it includes consequences for trying to submit false urine samples.

The policy change states students who provide false samples for mandatory drug tests may be suspended or expelled.

Students participating in sports and other activities have been required to take drug tests since 2002.

The district has had a few instances of students attempting to provide false samples to the district, Superintendent Donald Tylinsky has said.

The district is prohibited by law from removing students from instructional time because of failed drug tests. Students who fail a drug test lose privileges, such as driving to school or participating in a sport or activity for a specified period of time.

The change being discussed, however, would be for disciplining students for tampering with the test, not failing it, solicitor Matt Hoffman said.
