Cell Phone and Electronic Device Policy

Due to recent legislation taken by Harrisburg, Mastbaum has implemented a zero tolerance policy on cell phones and devices that are not assigned by the district. You can read more about this policy by clicking on this link.

Dear Mastbaum Families,

This year, Mastbaum is working hard to ensure every student can learn and grow by being at school regularly.  Being at school is important for learning, building friendships and participating in the school community.  We want to support your student’s success through attendance and engagement in school.

Why Attending Matters:
  • Missing just 2 days a month (or 10% of school) can impact your student’s chances of graduating on time.
  • School is essential for students to build friendships and learn how to be in  a community with their peers and adults.
  • Absences can signal problems like disengagement, academic struggles, or bullying, and therefore are important for us to pay attention to.
What We Need From You:
  • Follow health guidelines so that you know when to keep your student home due to illness and when to send them to school.
  • If your student will be absent, contact the school secretary at 215.400.7220.
  • Reach out of us if your student is struggling to come to school or if you are having challenges getting your child to school.  We are here to help.
  • Follow our school policies or expectations.
What You Can Do:
  • Set a consistent bedtime and morning routine.
  • Prepare for school the night before, ensuring homework is done and your student gets enough rest.
  • Talk to your student about the importance of school and attendance.
  • Keep track of the number of days your child has missed on a calendar in a visible location in the home.
  • Ask your student to assist with tracking the days.
  • Days can add up quickly. Airm to keep to 17 days or less in a year.
  • Schedule appointments before or after school, or at the very beginning or end of the school day to minimize the amount of time your student will be out of school.
  • Schedule vacations during district scheduled holidays or during  summer break.
  • Have backup plans for transportation.
  • Communicate with your child’s teacher, the front office or the school counselor about any concerns. Communication is key!
  • Encourage after school activities.
Our Promise to You:
  • We understand challenges that affect attendance and are here to help.
  • Use our resources, like the nurse or school counselors for support.
  • We will take attendance daily (as required by state law), communicate when your student has an unexcused absence, and help overcome barriers to attending regularly.

What Families Need to Know About Pennsylvania’s Compulsory Attendance Laws:

  • Pennsylvania requires parents and school districts to follow these steps when students are absent:

You can access additional attendance information by visiting the School District of Philadelphia’s website:  https://www.philasd.org/studentrights/attendance/.

 

We are asking that you complete the google form located HERE indicating you read and understand the School District of Philadelphia’s attendance policies and procedures.

Sincerely,

Mr. David Lon, Principal

Dear Mastbaum Families,

Welcome to the 2026-27  school year!  We are excited to build upon our recent successes, where we have established significant growth in building safety and student achievement, as well as a fun and energetic learning environment that celebrates students with numerous events, activities, and partnerships.

At Mastbaum, our school vision is “We build the future.”  As our students work to build the future for themselves and their communities, we work with you, the families, to be builders as well.

We all engage in the work of “building” in three different ways.  First, Mastbaum students are members of a safe and welcoming school community where their leadership is encouraged and nurtured.  Second, they receive rigorous academic programming in English, History, Math, Science, and electives courses.  Finally– and this is what makes Mastbaum unique– they engage in a field of intensive Career and Technical Education study: Automotive Technology, Carpentry, Culinary Arts, Electrical Technology, Film and Video, Graphic Design, Health-Related Technology, Plumbing Technology, Police Science, Sports Marketing, and Welding Technology.  In addition, we partner on-site with 12plus and Philadelphia Academies, Inc to help students realize their postsecondary goals.

This is the experience that sets us apart!  With the broad range of specialized skills that a student earns at Mastbaum, they have the ability to either enroll in college OR directly enter a skilled, high paying career field in such placements as the Navy Shipyard, SEPTA, PECO, PGW, Philadelphia Airport, Elliot Lewis, and many more

Important Policy Notice: Cell Phone Lockers for 2026–2027
To support our safe learning environment and in response to upcoming Pennsylvania state legislation restricting mobile devices in schools, Mastbaum High School will institute cell phone lockers for ALL students in grades 9 through 12 for the 2026–2027 school year.  A separate letter fully detailing the policy, daily procedures, and implementation guidelines will be sent under separate cover.

This is my eighth year as principal of Mastbaum, and I am looking forward to another great year in serving our school community.

Sincerely,

David Lon, Principal – dllon@philasd.org
