Reimagined CLASS Observation Training

A Reimagined CLASS Observation Training

We reimagined and redesigned CLASS® Observation Training to offer a more comprehensive training experience that leaves observers feeling more confident in their ability to effectively observe interactions, specifically across diverse settings.

The CLASS 2nd Edition Pre-K–3rd Observation Trainings help observers:

    • Build their understanding of equitable observations through new diverse examples, video activities, and explicit guidance on reducing bias and observing across various settings.
    • Collect more actionable data through new scoring strategies, formalized scoring protocols at the indicator level, and support to observe and document the type of learning experiences and activities occurring.
    • Certify and recertify across more age-levels by combining Pre-K, Transitional Kindergarten, and K-3rd into one single manual set, observation training, and certification processes.
Enhanced CLASS® Manual

An Enhanced CLASS® Manual

The CLASS Manual, expanded into our new Manual Set, has been carefully reviewed and intentionally enhanced to make meaningful interactions as defined by CLASS more equitable, inclusive, and accessible.

The CLASS 2nd Edition Pre-K–3rd Manual helps to:

  • Increase access to CLASS with the CLASS 2nd Edition: Pre-K–3rd Reference Manual, containing the research, theory, instructions on how to use CLASS in a CQI system, and impact of interactions, by being publicly available online.
  • Ease the observation process by combining age levels and giving observers the tools they need at their fingertips in the CLASS 2nd Edition: Pre-K–3rd Observation Field Guide.
  • Strengthen measures of quality with equity considerations and guidance embedded throughout the manuals, support for observing in diverse settings, and new item sets to collect the type of learning experiences occurring across classrooms.

A New Measure of Quality: CLASS® Environment

Take a holistic approach to supporting child outcomes by measuring and improving the elements of an environment that can fuel quality interactions with the CLASS Environment measure.

Used alongside the CLASS tool, CLASS Environment is built to:

  • Focus on the arrangements, displays, and types of materials within an environment that promote teachers’ engagement in meaningful interactions.
  • Support infant/toddler, and pre-K/K educators in creating and leveraging effective learning environments.
  • Streamline quality data collection into one system and one observation to reduce disruptions and investments while increasing data-driven improvement efforts.
