Bloomington, Ind., [December 2, 2025] — Hidden Lake Secondary School is pleased to announce the 
achievement of Level 4 certification in Marzano High Reliability Schools. Level 4 certification means 
Hidden Lake Secondary School has implemented “Standards-Referenced Reporting,” which requires 
teachers to report individual students’ progress related to specific standards.

The high reliability school (HRS) program was created by Marzano Resources to help transform schools 
into organizations that take proactive steps to ensure student success. Using a research-based five-level 
hierarchy, along with leading and lagging indicators, educators learn to assess, monitor, and confirm the 
effectiveness of their schools. 

This framework, based on 50 years of educational research, defines five progressive levels of 
performance that a school must master to become an HRS—where all students learn the content and skills 
they need for success in college, careers, and beyond. 

“As you move through the levels, it represents a complete transformation in how schools are run,” says 
CEO Robert J. Marzano. 

Schools must collect data and validate their performance to climb each level of the hierarchy. 
Certification is determined by Marzano Resources analysts in cooperation with school data teams. 

Using the HRS framework and indicators, schools can drive sustained, positive, and significant impacts 
on student achievement by synthesizing multiple complex initiatives into one harmonious system.
