Dr. Heather Short Approved as New Superintendent
In a special meeting held Tuesday, May 27, the Penn-Harris-Madison Board of School Trustees unanimously (7-0) approved the appointment of Dr. Heather Short as the district’s next superintendent effective July 1, 2025.
Nearly 50 P-H-M teachers, administrators, staff, family and friends showed up to express their overwhelming support of Dr. Short’s appointment.

Dr. Short, a lifelong educator who has dedicated her entire 31-year career to P-H-M, will succeed Dr. Jerry Thacker, who is retiring after 19 years of transformative leadership. Dr. Short has served as Assistant Superintendent for Instruction since 2017. During her tenure, P-H-M students have experienced consistent academic growth and achievement.
“I am deeply honored by the Board’s confidence and grateful to Dr. Thacker for his mentorship throughout my career,” said Dr. Short. “It has been the privilege of a lifetime to grow as a leader within this incredible district. I’m excited to continue working alongside our talented staff, dedicated families, and exceptional students to expand opportunities and ensure every child thrives.”
Under Dr. Short’s leadership, P-H-M ranks in the top 4% of Indiana districts based on ILEARN scores. The district also outpaces the state average by 20 percentage points in overall percent passing rates.
“There is no one better—or more qualified—to lead P-H-M’s continued path of academic excellence than Dr. Short,” said Chris Riley, President of the Board of School Trustees. “Her academic expertise and visionary leadership in developing rigorous, relevant curriculum have been key to our students’ success. Dr. Short was the Board’s clear and unanimous choice for superintendent.”

P-H-M is home to some of Indiana’s highest-performing public schools in both English/Language Arts and Math. Prairie Vista Elementary ranks #3 in the state, while Discovery Middle School ranks #2. In Spring 2024, P-H-M’s IREAD pass rate was 86.8%, surpassing the state average of 82.5%. Three P-H-M elementary schools—Prairie Vista (97.7%), Northpoint (95%), and Horizon (95.3%)—achieved pass rates above 90%. Included in her district-wide academic strategy was a robust Response to Intervention (RtI) program and expanded summer offerings that support both enrichment and remediation.
Dr. Short’s leadership journey reflects deep roots and unwavering commitment to P-H-M. She began her career as a classroom teacher before serving as an Instructional Leader and High Ability Coordinator. Click here to learn how Dr. Short and Board Trustee Katie Bell’s paths crossed when Dr. Short was a 3rd grade teacher at Northpoint. In 2004, she became principal of Prairie Vista Elementary. Recognizing her talent for professional growth and instructional excellence, Dr. Thacker appointed her in 2007 as P-H-M’s first Director of Professional Development—a role she held for a decade before being named Assistant Superintendent.
Throughout her career, Dr. Short has been deeply committed to developing others. She co-created a nationally recognized leadership development program designed to build internal capacity among P-H-M educators and administrators. Her strategic focus on professional development has empowered teachers at every level—from new educators to veteran principals—through initiatives like the annual Literacy Summit and the New Teacher Series.

As Assistant Superintendent, Dr. Short has combined her instructional leadership with strong fiscal stewardship. She has overseen the management of multimillion-dollar budgets and successfully secured hundreds of thousands of dollars in state grants—investments that have directly enhanced classroom instruction, expanded student programs, and strengthened districtwide operations.
“Dr. Short possesses one of the most valuable qualities a leader can have: the ability to build genuine relationships,” said Dr. Thacker. “She makes personal connections with teachers, principals, staff, families—and most importantly, students. She understands the P-H-M culture because she helped build it. There is no one more fitting to serve as the next superintendent.”
After the Board approved Dr. Short as the district’s new leader, Board members shared well wishes and comments. Trustee Katie Bell (elected in November 2024) talked about how things have come full circle for her as a former student of Dr. Short’s when she taught 3rd grade gifted and talented students at Northpoint. The two were actually featured in an article that ran in the South Bend Tribune in March 2003. The article featured Dr. Short teaching her students how to use PowerPoint for their Geography reports on Asia. Click here to read the original story.

Fast forward to 2013 to when Dr. Short was P-H-M’s Director of Professional Development, she interviewed Bell for a teaching position. Bell was hired as a kindergarten teacher in 2016 at Prairie Vista Elementary School and Dr. Short led the professional development for all new teachers. “Dr. Short and I are a testament that it’s never goodbye, it’s always see you later,” Bell said. “And I think that shows the true impact of a teacher, that they are in your lives forever, and that you will always remember them.”

Spotlight on Discovery Middle School
Principal Elizabeth Cunha welcomed the Board of School Trustees to Discovery on Monday, May 19. A welcoming, warm reception awaited Board members, P-H-M Administrators, patrons and families as they arrived. In the lobby, the student orchestra performed while “StarBuddies” offered free coffee!
When the Board Meeting began, Principal Cunha explained the “StarBuddies” program and shared that recently the Discovery Band earned the ISSMA J.M.E. All-Music Award for 2024-2025, along with highlight many other student achievements. Click here to view Principal Cunha’s presentation.

P-H-M Named 2025 Best Community for Music Education
For the 12th consecutive year, Penn-Harris-Madison School Corporation was named among the 2025’s Best Communities for Music Education (BCME) in the country by the National Association of Music Merchants (NAMM) Foundation! P-H-M has received this recognition more than any other school district in Indiana!
This year NAMM has named 935 school districts as the nation's Best Communities for Music Education, and P-H-M is one of them! The award program recognizes and celebrates outstanding efforts by teachers, administrators, parents, students, and community leaders who have made music education part of a well-rounded education. Designations are made to districts that demonstrate an exceptionally high commitment to and access to music education.
In P-H-M elementary schools, music class is part of the regular curriculum following state standards. Students are instructed in both vocal and instrument classes. Beginning in 6th grade, P-H-M students at our three middle schools (Discovery, Schmucker and Grissom) have the opportunity to choose choir, orchestra or band as their music elective. Students at Discovery also have the option of choosing Piano Lab. Schools from elementary all the way up to Penn High School also perform musicals.

Penn High School offers the Fine Arts & Communication Academy as part of its unique academy structure. The seven academy design provides Penn students with relevant and meaningful coursework taught in smaller, supportive environments where each student is known well by his teacher and peers. Nearly a third of Penn’s total 3,500 students are enrolled in the Fine Arts Academy with the majority being involved with music programs, either Choir, Orchestra, Band or another music program.

To qualify for the Best Communities designation, P-H-M answered detailed questions about funding, graduation requirements, music class participation, instruction time, facilities, support for the music program, and community music-making programs. Responses were verified with school officials and reviewed by The Music Research Institute at the University of Kansas. Research into music education continues to demonstrate educational/cognitive and social skill benefits for children who make music.
In a series of landmark studies by scientists and researchers at Northwestern University a link was found between students in community music programs and life-long academic success, including higher high school graduation rates and college attendance. In another study from the University, it was discovered that the benefits of early exposure to music education improves how the brain processes and assimilates sounds, a trait that lasts well into adulthood. Beyond the Northwestern research, other studies have indicated that music education lays the foundation for individual excellence in group settings, creative problem solving and flexibility in work situations, as well learning how to give and receive constructive criticism to excel.
Mr. Cornelison Named VFW District 3 Teacher of the Year
Discovery Middle School is proud to announce that in late March 7th grade Social Studies teacher Les Cornelison was named the Veterans of Foreign Wars (VFW) Teacher of the Year for Indiana’s District 3 for 2025. The award recognizes exceptional educators who instill the values of civic responsibility, patriotism, and service in their students.
Mr. Cornelison, unaware he had even been nominated, was humbled to receive the news. He credits fellow educator Ryan Towner for submitting the nomination that led to the recognition. “I am very honored to be thought of in this manner,” Les shared.
Each year, the VFW selects one teacher from each state district for this distinction. Winners receive a stipend for both professional development and classroom resources. As the District 3 honoree, Mr. Cornelison is now eligible for consideration at the state and national levels.

Les Cornelison’s life has been a journey of service. He began in the United States Marine Corps from 1990-1994.

Following his military service, Les transitioned into the fire service, rising through the ranks from firefighter to Fire Captain and ultimately Fire Chief with both the Penn Township and Osceola Fire Departments. While working, he pursued his MBA part-time at IU South Bend.
He later served as a U.S. Diplomat in locations including China, the Philippines, Washington D.C., and Afghanistan. After retiring in 2020 and overcoming a spinal injury, Les found a new path in education—bringing decades of real-world experience into his classroom.

“My biggest drive is I want to be adding value to my students,” said Les. “I have my pension. I don’t need to work, but I want to give back and help develop a love of learning in my students.”
We congratulate Mr. Cornelison on this well-deserved honor and thank him for his continued dedication to serving others, both in and out of the classroom!
Along with earning the Transition to Teaching licensure, Mr. Cornelison earned two other degrees from IUSB: Bachelors of Science in Economics, Statistics Concentration and a Masters of Business Management and Administration. You can read more about what led Mr. Cornelison to transition into education.
Discovery Counseling Team Earns RAMP designation

Change to 2024-25 School Year Calendar
Due to the absence of local, state, or national elections on Tuesday, May 6, 2025, all P-H-M schools will be in session on Tuesday, May 6, 2025. P-H-M will no longer have a Recess Day on this date.
As a result, the last day of school for students will now be Thursday, June 5, 2025. This is one day earlier than previously scheduled. P-H-M Teachers Association worked collaboratively with the District Administration to make these calendar changes.
Indiana law requires schools to be in session for 180 days each year. If necessary, P-H-M can utilize up to three weather-related eLearning days, as permitted under Indiana law (HB-1093). If additional makeup days are needed, they will be added to the end of the school year, following the new last student day, Thursday, June 5, 2025. Currently, no eLearning days have been called.
The new 2024-2025 school year calendar is posted on the P-H-M website, click here to view the updated calendar.
