Demographics

Neal Math and Science Academy (NMSA) in North Chicago serves 525 students and is progressing toward Level 3 High Reliability Schools certification after successfully completing Levels 1 and 2. The school began their journey in 2021, focusing on improving culture, student outcomes, and supporting instruction. With 99% of the students being economically disadvantaged, NMSA has been dedicated to creating an environment where all students can thrive. Michael Grenda serves as the principal.

Neal Math and Science Academy's Challenge

For the last 25 years, Michael Grenda has been seen as a “change agent” in his school district of North Chicago. When he was asked to come to Neal Math and Science Academy in 2020, he was determined to make a long-lasting impact on staff and student success by doing it the right way with help and guidance from experts.

“I wanted to meet my staff where they were at. … It was more about helping them understand that these elements and strategies are aligned to student outcomes … and what they really need is professional development that they can take into their classroom the next day and utilize it to support the work they do,” commented Grenda.

Principal Grenda began researching effective strategies for middle school improvement. His efforts led to discovering Marzano’s High Reliability Schools (HRS) framework, which became the foundation for his approach. After attending an HRS Summit online during the COVID-19 quarantine, principal Grenda and the new administration team adopted the HRS framework as their guide for driving change and improvement in the school.

Implementing this framework presented its own challenges, primarily due to the lack of a common language among staff, which hindered effective collaboration and sharing of best practices. The staff was also accustomed to working independently rather than collaborating as a team. Overcoming this required shifting mindsets to focus on student outcomes over teacher actions and ensuring that new strategies were seen as tools for improvement and not mere checklists.

Implementation

“We were very intentional . . . I would introduce strategies every month not just to the staff but also to the students. We let them know what the focus was each month, and it helped them know what we were looking for in a classroom and gave them that sense of accountability.”

The process began with a focus on Level 1 of the HRS framework, which emphasizes creating a safe, supportive, and collaborative culture. First, surveys were conducted to identify strengths and areas for improvement.

“Once we decided that this was the right work for us and this was the road map we were going to use, we did an audit on what things were going well and what things were not going well,” explained principal Grenda. This data-driven approach helped identify quick wins, boosting staff morale.

During the audit, it was clear that instructional strategies were inconsistent across different classrooms and teachers. To establish more reliable and assessable teaching methods, an instructional framework was introduced, starting with a foundational set of nonnegotiables that their school created as a team and called the “NMSA Way.” This helped build common practices that everyone could agree upon and be held accountable for.

But teachers and administrators weren’t the only ones accountable—students were responsible for their own learning as well, which significantly contributed to their success.

“We were very intentional. … I would introduce strategies every month, not just to the staff but also to the students. We let them know what the focus was each month, and it helped them know what we were looking for and gave them that sense of accountability.”

This approach ensured that students, staff, and parents were all aligned, creating a cohesive and supportive learning environment. Once the staff was more comfortable with these foundational practices, specific strategies from the New Art and Science of Teaching (NASOT) framework were introduced to the staff. This was done through monthly instructional focuses, where one or two NASOT strategies were highlighted.

Principal Grenda emphasized that the elements and strategies outlined were directly tied to student outcomes. The goal was not to evaluate teachers based on whether they performed specific tasks, but to assess how these strategies impacted student learning. This shift in perspective helped to align the staff’s efforts as they began to understand that the purpose of these instructional strategies was to enhance student achievement rather than simply complying with a prescribed set of teaching behaviors.

“The New Art and Science of Teaching framework wasn’t about checking off a list. It was more about helping teachers understand that instructional elements and strategies should be aligned to student outcomes,” explained Grenda.

After some practice, the team successfully developed a common language around instructional strategies, enabling more effective communication and collaboration. This aligned with Level 2 of the HRS framework, which focuses on effective teaching in every classroom.

Both administrative and peer walkthroughs were conducted to observe how teachers were implementing the NASOT strategies in their classrooms. These walkthroughs were approached as learning opportunities rather than evaluations. It allowed them to see the strategies being applied in real time.

Principal Grenda noted that the exchange of positive feedback became a powerful tool, with teachers expressing appreciation and admiration for each other’s techniques. For instance, one teacher might email a colleague to say, “I was really impressed by how you chunked content during your fourth-period class. I’m definitely going to incorporate that into my own teaching.” This kind of interaction not only reinforced the effectiveness of the strategies but also built a collaborative and supportive culture among the staff.

Results

Since implementing Level 2 of the HRS framework in 2023, Neal Math and Science Academy has seen significant improvements in student performance, earning the 2024 Illinois Summative Designation as a “Commendable School.” This recognition celebrates Neal Math and Science Academy as a school with no underperforming student groups and a graduation rate exceeding 67%, underscoring its commitment to elevating student success across the board.

Preliminary data from 2023 to 2024 show a significant reduction in students not meeting grade-level standards, with a 46% decrease in students not meeting grade-level reading standards, and a 32% decrease in students not meeting grade-level math standards, marking strong growth in state testing scores at Neal Math and Science Academy (Illinois Report Card, 2023; Illinois Report Card, 2024). Teachers report that students are now more engaged, actively participating in their learning, and setting personal goals. This shift has fostered a more positive and focused learning environment for all.

Why High Reliability Schools?

Dr. Marzano’s vision for K–12 education is simple: the vast majority of schools can be highly effective in promoting student learning. To show how, he created the Marzano High Reliability Schools framework. This framework, based on 40 years of educational research, defines five progressive levels of performance that a school must master to become a high reliability school—where all students learn the content and skills they need for success in college, careers, and beyond.
