iReady is a widely used adaptive assessment tool that helps educators understand students’ strengths and weaknesses in reading and math. The iReady Diagnostic Score is a measure of a student’s academic performance and readiness for their grade level. But what exactly is considered a “good” iReady Diagnostic Score?

A “good” score typically means that a student is performing at or above their grade level. iReady categorizes scores into different performance levels:

• Below Grade Level
• Early On Grade Level
• On Grade Level
• Above Grade Level.

The goal for most students is to be On Grade Level or Above by the end of the academic year.

Understanding i-Ready Placement Reports: A Guide for Parents.

When reviewing your child’s i-Ready Diagnostic reports, you may see two types of placements: Absolute Placements and Relative Placements. These help you understand your child’s learning progress in Reading and Math.

What Do These Placements Mean?

1. Absolute Placement
   • Represents the grade level that matches your child’s current performance.
   • Example: If a third-grade student performs at a first-grade level, their absolute placement would be Grade 1.
   • Used to assess how close a child is to meeting grade-level expectations based on college- and career-readiness standards.
2. Relative Placement
   • Compares your child’s performance to their actual grade level.
   • Example: A third-grade student performing at a first-grade level would have a relative placement of Two Grade Levels Below.
   • Used to identify students who may need extra support or intervention, providing a broader picture of their academic growth.

Understanding the Different i-Ready Placement Levels.

Absolute Placement Levels

• Early On Grade Level (e.g., Early 3 for a third-grade student)
  • Students have partially met grade-level expectations and benefit from on-grade instruction.
• Mid Grade Level (e.g., Mid 3 for a third-grade student)
  • Students meet the minimum requirements for their grade level and benefit from instruction in later on-grade topics.
• Late Grade Level (e.g., Late 3 for a third-grade student)
  • Students have successfully met or surpassed grade-level expectations and may be ready for early instruction in the next grade level.
• Below Grade Level (e.g., Grade 2, Grade 1, or Kindergarten for a third-grade student)
  • Students need remediation focused on below-grade material to address learning gaps.
• Above Grade Level (e.g., Grade 4 for a third-grade student)
  • Students benefit from above-grade instruction, having met or surpassed grade-level expectations.

Relative Placement Levels.

• Early On Grade Level
  • Students have partially met grade-level expectations and benefit from continued grade-level instruction.
• One Grade Level Below
  • Students are approaching grade-level expectations and benefit from both grade-level instruction and targeted support.
• Two Grade Levels Below
  • Students need extra support with foundational skills to prepare for grade-level instruction and may require formal intervention.
• Three or More Grade Levels Below
  • Students require significant support in foundational skills and formal intervention to help them catch up to their grade level.
• Mid, Late, or Above Grade Level
  • Students at this level have met or exceeded grade-level standards and benefit from advanced instruction or enrichment activities.

How These Placements Are Used

• Schools use these placements to track progress, determine interventions, and measure academic growth.
• 3-Level Placements (green, yellow, red) are often used for intervention screenings, adjusting across the school year.
• 5-Level Placements (ranging from Above Grade Level to Three or More Grade Levels Below) provide consistent measurement across the year.
• Some students may receive a Max Score, indicating that they have exceeded the tested grade levels and do not require further instruction in that domain.

What Can Parents Do?

• Stay Informed – Review your child’s placement levels and discuss progress with their teacher.
• Support at Home – Encourage reading, math practice, and interactive learning activities.
• Communicate with Educators – If your child is placed below grade level, ask how you can help at home and what interventions the school is providing.

Basically i-Ready Diagnostic used 5 different Grade placement levels. The goal for most students is to be On Grade Level or Above by the end of the academic year.

How to Read Your Child’s i-Ready Placement Score on the Chart Above

Understanding your child’s i-Ready Diagnostic score can help you track their progress and identify areas where they may need support. Here’s how to read the placement table for Math, above:

1. Find Your Child’s Grade Level

Look at the first column of the placement table and locate your child’s current grade level. This row will show where their score falls in relation to their grade.

2. Locate Your Child’s Score Range

Find the range that includes your child’s score. The column label for that range tells you their grade-level placement.

3. Understand the Placement Levels

Each score falls into a color-coded category:

• Green (On Grade Level)
  • Early On Grade Level (light green)
  • Mid Grade Level (darker green)
  • Late Grade Level (darker green)
• Yellow (One Grade Level Below) – Some additional support is needed.
• Orange (Two Grade Levels Below) – Significant support is needed.
• Red (Three or More Grade Levels Below) – Intensive support is needed.
• Gray – This score is not possible for the selected grade.

Use these color codes for the iReady diagnostic grade level chart, above.

Example: How to Interpret a Score

• Student A is in 3rd grade and received a score of 500 in Reading.
• Looking at the 3rd-grade row, a score of 500 falls in the 474-510 range, which is a 2nd-grade placement.
• Since this range is shaded yellow, Student A is considered one grade level below in Reading.

Why This Matters

Your child’s i-Ready placement score helps teachers personalize their learning. If your child is below grade level, schools will provide extra support to help them catch up. If they are on or above grade level, teachers will continue to challenge them to grow.
