Truenorthlogic Calibration

Valid, Defensible Observations

Truenorthlogic Calibration is an easy and reliable tool to score and certify observers who conduct teacher and principal observations, creating consistency and fairness in the evaluation process and fostering inter-rater reliability.

Fairness in the evaluation process occurs when observers follow similar processes, accurately interpret district-defined rubrics, and have the necessary skills to gather objective and representative evidence of teaching practice. Truenorthlogic Calibration is an easy and reliable tool to score and pursue certification of observers who conduct teacher and principal observations.

Used to drive ongoing professional development, Truenorthlogic Calibration manages calibration events with strong workflow and access control capabilities, precisely measuring an individual observer’s skills and accuracies.

Master-scored videos are aligned to any research-based rubrics. Truenorthlogic Calibration provides the true score and actual score report, with the option to release the scores at an appropriate time to the individual observers.

Truenorthlogic Calibration was built in collaboration with Teaching Learning Solutions, an esteemed organization that conducts observer certification trainings and analyzes data to determine degrees of inter-rater reliability based on research, best practices and statistical significance.

During calibration training, observers are able to practice their ability to collect defensible evidence and select valid ratings, preparing them to conduct real-world observations in which the outcomes are consistent and precise.


Truenorthlogic Calibration Benefits Across the Organization

Administrators are able to determine district-wide, inter-rater reliability to ensure accurate observations.

Educators can trust the observation process and know they are being evaluated fairly and consistently.

See how districts across the country are using Truenorthlogic Calibration to create an efficient and effective educators.


Truenorthlogic Calibration includes:

  • Relevant, high-quality, master-scored videos aligned with district rubrics, providing observers with realistic observation scenarios. School districts may also add their own scored videos.
  • An easy-to-use scripting tool to help observers demonstrate their ability to collect defensible evidence and select valid ratings, resulting in consistent and precise outcomes for evaluations.
  • Three distinct accuracy measures which explain the observer’s accuracy, how observers compared to their cohort, and how closely aligned the cohort was to the accuracy measure. Automated scoring provides instant access to individual scores and certification results.
  • Individual proficiency-level scores identifying observer strengths and weaknesses, driving professional growth decisions for observers and supporting consistent practices throughout the year.

Individual participants receive an individualized report that describes how they performed on three quantitative measures of performance.


Truenorthlogic Calibration is a key component of the Truenorthlogic Platform, with tools offering professional development content and management, educator evaluation and more. The Truenorthlogic Platform fully supports the cycle of continuous educator improvement.

What Our Clients are Saying

I found Truenorthlogic Calibration to be a great tool for our state office. We used this tool to facilitate statewide principal reliability practice and the final certification assessment. It allowed the participants a platform to uniformly enter data. I was then able to review individual results to analyze data trends and easily track completion rates and areas needing support.
