Understanding Your Child's MAP Test Scores
Demystify NWEA MAP Growth scores. Learn what RIT scores and percentiles mean for your child's academic progress and how to use this data effectively.
What Are MAP Test Scores?
MAP Growth (Measures of Academic Progress) is a computer-adaptive test used by many schools in the US and Canada to assess students from kindergarten through 8th grade in subjects like math, reading, language arts, and science. Unlike traditional tests, MAP Growth is designed to measure your child's unique learning level and track their academic growth over time. The scores provide valuable insights into what your child knows and is ready to learn next, helping educators tailor instruction to their specific needs.
Key Components of MAP Scores: RIT and Percentiles
When you receive your child's MAP Growth report, you'll typically see two main types of scores: the RIT score and the percentile rank. It's important to understand what each of these numbers represents.
The RIT (Rasch unIT) score is a unique scale that indicates your child's achievement level. It's an equal-interval scale, meaning that a difference of 10 points on the RIT scale represents the same amount of growth regardless of where it occurs on the scale. For example, a 10-point gain from a RIT of 180 to 190 is equivalent to a 10-point gain from a RIT of 210 to 220. This score helps measure how much your child has learned and their current instructional level. The RIT score is specific to the subject tested (e.g., Math RIT, Reading RIT).
Understanding Percentile Ranks
The percentile rank tells you how your child's RIT score compares to other students in the same grade who took the test during the same testing window (e.g., fall, winter, or spring). For example, if your child scores in the 75th percentile for reading in the fall, it means they scored as well as or better than 75% of the students in their grade who took the same test nationally.
It's crucial to remember that a percentile rank is a comparison tool, not a measure of mastery. A student scoring in the 50th percentile is performing at the average level for their grade, not necessarily that they only know 50% of the material. Many programs use percentiles in the 95th–98th range as a benchmark for gifted identification, but it's always best to check with your school or district for their specific criteria. Percentiles can vary by subject, grade, and testing season (fall, winter, spring).
Interpreting MAP Scores: What's a 'Good' Score?
The concept of a 'good' MAP score is relative and depends on several factors, including your child's starting point, their growth trajectory, and the specific goals set by their school. Instead of focusing solely on a single score, it's more beneficial to look at your child's progress over time. Are they showing consistent growth from one testing period to the next? Are they moving closer to grade-level expectations?
NWEA provides general norm data that shows average RIT scores for different grades and testing periods. For instance, average RIT scores for reading and math will naturally increase as students progress through the grades. Your child's teacher is the best resource for understanding what their specific scores mean in the context of their classroom learning and individual progress. They can help you interpret the detailed reports that accompany the MAP Growth assessment.
How to Use MAP Score Information
MAP Growth scores are designed to be actionable. They help teachers identify areas where students are excelling and areas where they might need additional support. This information allows educators to differentiate instruction, form small groups for targeted interventions, and provide enrichment activities for students who are ready for more challenging content.
As a parent, you can use these scores to have informed conversations with your child's teacher about their academic journey. You can also use the insights to support learning at home by providing resources or activities that align with their current instructional level and areas for growth. Many schools also offer parent portals where you can view your child's scores and progress reports.
MAP Growth and Gifted Programs
Some school districts utilize MAP Growth scores as one of the measures for identifying students for gifted and talented programs. While there isn't a universal cutoff, many programs consider students scoring in the higher percentiles (often in the 95th–98th percentile range or higher) as potential candidates. However, this is just one piece of the puzzle, and schools typically use a combination of assessments and other criteria for gifted identification. Always verify the specific criteria and process with your child's school or district for accurate information.

Common questions
How often are MAP tests given?
MAP Growth tests are typically administered multiple times a year, often in the fall, winter, and spring, to track student progress throughout the academic year.
Where can I see my child's MAP scores?
Your child's MAP scores are usually shared by their teacher or can be accessed through a school-provided parent portal. The school administration or your child's teacher can guide you on how to access these reports.
Are MAP scores used for grading?
MAP Growth scores are primarily diagnostic and formative assessments used to measure growth and inform instruction. They are generally not used for direct grading purposes, though they provide valuable data that can influence classroom instruction and support.
