BACKGROUND INFORMATION



Developed for children birth-7.11 years old
Standardized test with nationally representative
sample of 2500 children
Bias reviews on all items conducted for the following
areas of concern:





Gender
Ethnicity
Cultural
Regional
Socio-economic
OVERVIEW OF ASSESSMENT
NORM-

Allow for comparisons of a child’s performance with that of
a reference group --> children of the same age

Generates normative scores:

Standard scores/Developmental Quotients

Mean = 100, Standard Deviation = 15

Scaled scores

Mean = 10, Standard Deviation = 3

Norm-referenced tests follow standardized administration
procedures, meaning that administration is conducted in a
uniform and consistent way so that a child’s performance
can be compared fairly to the performances of other
children.

Scoring and Interpreting
ADMINISTRATION


STARTING POINT: first item administered in each
sub-domain. Chosen by the evaluation team. Often
based on the child’s chronological age
BASAL: Functional level at which child shows
mastery of tasks
 Child

must score 3 consecutive 2-point responses
CEILING: Level at which tasks become too difficult
 Child
must score 3 consecutive 0-point responses
What is the raw score for the
Gross Motor Subdomain?
Step 2
Test in reverse
order until
basal is met
Step 1
Start Point
GM 20
Step 3
Continue
testing
forward until
ceiling is met
Calculating the Raw Score


For each subdomain add up the 2 scores and the 1
scores to determine the raw score.

REMEMBER: the basal assumes that the child would get a
score of 2 for all of the preceding tasks, so you must add in
these sums to the raw score.

Transfer the raw score onto the Scoring Profile on the front of
the scoring booklet (2nd column of large table)
Use the raw scores to determine the percentile rank and
scaled scores for each subdomain using Appendix B.
Scoring continued…



Use exact chronological age and obtained raw scores
to derive (Appendix B):
 Age Equivalents (subdomains)
 Scaled Scores (subdomains)
 Percentile Ranks (subdomains & domains)
Determine the Sum of Scaled Scores for each domain
and then use these numbers to derive (Appendix C):
 Developmental Quotients (domains)
 Confidence Intervals (domains)
Create subdomain & domain profiles

Enter subdomain raw
scores.
Use Appendix A to
obtain age
equivalent (AE).
Use Appendix B to
obtain percentile
rank (PR) and scaled
score.
Total subdomain
scaled scores within
each domain. Then
total the totals.

DOMAIN & BDI-2
TOTAL SCORES
Transfer domain
scaled score totals
to sum of scaled
scores boxes.
Use Appendix C to
obtain the DQ, PR,
and Confidence
Interval (90% or
95%) for all 5
domains and the
BDI-2 Total.

COMPOSITE PROFILE
Transfer the developmental
quotients to the appropriate
boxes.
Place a dot (or an X) in the
column for the obtained DQ.
Connect the dots (or X’s) to
obtain a norm-referenced profile
of the child’s performance on the
composites.
Do not connect the domains to the
total score.
If a domain was not administered
do not connect lines through that
domain.
