About the K–2 Scale Maintenance

Starting July 25th, the K-2 MAP Growth test scores will use an updated methodology. Because of this “scale maintenance,” you should avoid making comparisons between MAP Growth K–2 scores from before and after July 25 2020, as shown on MAP Growth reports. Instead, you can use this conversion file to evaluate how historical MAP Growth K-2 scores would look with the new methodology applied. For more background, see the following resources:

  • FAQ (Introduction and frequent questions)
  • Research Summary (Impact of changes to K–2 scoring)

 

Evaluating decisions that were based on prior scores:

Although historical MAP Growth K-2 scores reflected a previous methodology, those scores are not incorrect. Any decisions made based on those scores can be considered valid because they relied on using the best data available at the time. NWEA always encourages the use of multiple data points in making decisions about the performance of students.

Example Uses of the Conversion File

  • To see how student performance on the MAP Growth K-2 assessment has changed over time, you could sort columns in different ways or import the data into a reporting tool.

  • For a quick comparison with this year’s score, use the last two columns—Fall 2020 RIT and Fall 2020 Achievement Percentile.

    Note: These Fall 2020 columns will appear blank for the years before 2019, because any comparison would not be useful.
