DEVELOPMENTAL DELAY SCREENING LATEST
UPDATED 2026-2027 ACTUAL FINAL EXAM PREP
WITH WELL ELABORATED PRACTICE QUESTIONS
AND 100% CORRECT DETAILED ANSWERS WITH
CERTIFIED RATIONALES PLUS RELIABLE ANSWER
KEY A+ GRADED MOST RECENT!!!
This examination contains multiple-choice questions covering developmental
surveillance, screening tools, milestone expectations, red flags, referral criteria,
and interdisciplinary management. Select the single best answer for each question.
Correct answers are indicated in bold. Rationales are provided in bold italics
following each question.
1. What is the most successful way to ensure early detection of developmental
issues in children from birth to age 5?
A. Through the clinical judgment of an experienced practitioner
B. Through periodic developmental-behavioral screening using a formal
measure or procedure
C. By relying solely on parental concerns
D. Through routine pediatric brain scans
Rationale: While clinical judgment and parental concerns are valuable
components, research demonstrates that the most reliable method for early
detection is periodic developmental-behavioral screening using standardized,
validated tools. Clinical judgment alone identifies only about 30% of children
with developmental delays, missing 70% of those with problems. Standardized
,screening provides objective, comparable data that reliably discriminates
children who need further assessment from those who do not.
2. Developmental-behavioral screening is BEST defined as:
A. Informal observation of a child's development in a natural setting
B. Analysis of a video-taped session of a child interacting with a clinician
C. A brief, easy-to-complete formal test that reliably discriminates children
who should be referred for further assessment from those who should not
D. A comprehensive diagnostic evaluation to determine eligibility for services
Rationale: Developmental-behavioral screening is specifically defined as a brief,
standardized formal test of children's developmental skills that reliably
discriminates those who should be referred for more comprehensive assessment
from those who should not. This distinguishes screening from surveillance
(ongoing observation) and diagnostic assessment (comprehensive evaluation).
3. According to the American Academy of Pediatrics, at which ages should all
children receive formal developmental screening?
A. 6, 12, and 18 months
B. 9, 18, and 30 months
C. 12, 24, and 36 months
D. 2, 4, and 6 years
Rationale: The AAP recommends that all children receive developmental
screening at 9, 18, and 30 months of age, in addition to surveillance at every
well-child visit.
4. At what ages does the AAP specifically recommend screening for Autism
Spectrum Disorder?
,A. 12 and 18 months
B. 18 and 24 months
C. 9 and 18 months
D. 24 and 36 months
Rationale: The AAP recommends autism-specific screening at the 18- and 24-
month well-child visits.
5. What is the primary purpose of a developmental screening tool?
A. To provide a definitive diagnosis of a developmental disorder
B. To identify children who may need further comprehensive assessment
C. To determine eligibility for special education services
D. To replace the clinical judgment of a pediatrician
Rationale: Developmental screening is defined as a brief, formal test that
reliably discriminates children who should be referred for further assessment
from those who should not. It is not diagnostic and does not determine service
eligibility.
6. The Denver Developmental Screening Test (DDST) assesses which four
domains?
A. Gross Motor, Fine Motor, Physical, Emotional
B. Gross Motor, Fine Motor, Language, Social Skills
C. Psychomotor, Fine Motor, Intellectual, Emotional Skills
D. Psychomotor, Emotional, Intellectual, Social Skills
Rationale: The DDST screens four domains: gross motor, fine motor-adaptive,
language, and personal-social skills.
, 7. Which of the following is a parent-completed questionnaire used for
developmental screening in children from 1 month to 5.5 years of age?
A. M-CHAT-R
B. PEDS
C. ASQ-3
D. DDST
Rationale: The Ages and Stages Questionnaire, Third Edition (ASQ-3) is a
parent-completed screening tool designed for children from 1 month to 5.5 years
of age. It covers five developmental domains: communication, gross motor, fine
motor, problem solving, and personal-social.
8. The Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) is designed
to screen for autism spectrum disorder in children aged:
A. 16 to 30 months
B. 12 to 18 months
C. 24 to 36 months
D. 6 to 12 months
Rationale: The M-CHAT-R is a parent-report screening tool specifically
designed for toddlers aged 16 to 30 months to assess risk for autism spectrum
disorder.
9. Developmental surveillance differs from developmental screening in that
surveillance:
A. Uses standardized, validated tools at specific ages
B. Is an ongoing, longitudinal process performed at every well-child visit
C. Provides a definitive diagnosis of developmental delay
D. Is only performed when parents express concern
