School District of Philadelphia PHILADELPHIA - The Philadelphia school board unanimously voted to adopt a "welcoming sanctuary schools" resolution, promising more training for staff on how to respond to Immigrations and Custom Enforcement officials and assuring immigrant students and families they will be safe from immigration authorities while at school or school activities.The vote Thursday comes after months of negotiations with Juntos, an immigrant rights advocacy group in South Philadelphia, that pushed the district to pass the resolution as the first step in a larger platform seeking language equity, improved cultural instruction and other educational justice reforms.
