RAVE-O includes a complete assessment system with frequent progress monitoring designed to work alongside your standardized tests to give the full picture of each reader’s development. POSSUM checks occur after every unit and evaluate the multiple components of reading. These checks are the basis for differentiated recommendations.

RAVE-O formal assessments

Test knowledge and retrieval of concepts taught within the program.

Standardized tests

Measure how well students apply what they’ve learned to new material.

Differentiation Guides are used after POSSUM checks and assessments to ensure that the areas of challenge are given targeted and specific recommendations.

Assessment tools

Four tools, one complete picture.

Each assessment type covers a different dimension of reading growth — from placement through fluency, unit mastery, and ongoing observation.

Placement Tests

Determine the right entry point for each student before instruction begins.

Fluency Checks

Quick, frequent checks that track oral reading fluency lesson over lesson.

Unit (POSSUM) Assessments

Comprehensive tests at the end of each unit measure retention and mastery.

Assessment Checklists

Ongoing observational tools for teachers to track qualitative progress in class.

What RAVE-O assessments measure

Multiple components of the reading brain, monitored.

Because RAVE-O is multi-componential in its approach, each of the POSSUM components are measured along with fluency and their use in connected text. This allows teachers to better understand a reader’s growth over time and use the differentiation tools to address areas of challenge.

Progress monitoring cadence

Pre-program

Placement test establishes each student’s starting point.

Each lesson

Quick fluency checks track moment-to-moment progress.

Each unit

Unit assessments confirm mastery before moving on.

After Each Module

Mid and post-program standardized testing checkpoint.
