Scoring and Interpreting Developmental Scores

The document provides instructions for scoring a developmental assessment with the following key steps: 1. Tally check marks in each developmental domain and record the raw scores. 2. Convert raw scores to scaled scores using a provided table to standardize scores across ages. 3. Add the scaled scores to derive the standard score/developmental index, which has a mean of 100 and standard deviation of 15, and interpret scores using provided thresholds.

HOW TO SCORE1.

Tally the number of check marks ( / ) in each domain and record all this in the
section labeled “Total Score”. (RAW SCORE)2.Transfer the raw score for each domain in the table
below. Using the Scaled Score Equivalent of Raw Scores Table,

34 HOW TO SCORE3.Change raw scores into scaled scores a. After you have derived the raw
scores for each domain, refer to the Scaled Score Conversation Tables. Locate the table for the age
of the child. Look for the raw score he obtained in each domain. The corresponding Scaled Score for
this printed in the column labeled “ Scaled Scores.”

35 b .After you have obtained the child's Scaled Score for each of the 7 domains, enter these in the
designated boxes in the Checklist's cover sheet.c. Plot these on the graph as well. Make sure you
use the columns Designated for the child's age.

36 Deriving the Standard Score or Development Index


Add the Scaled Score of each of the seven domains. This is called the sum of the Scaled Scores.
Theoretically the sum cannot be less than 7 or more than 133. Turn the Table of Standard Scores in
the manual. Locate the Sum of Scaled Scores that you arrived at, and then find the corresponding
Standard Score for this which is printed in the column labelled “Standard Scores.”Standard Scores
have a mean of 100 and a standard deviation of They are interpreted as follows:
