DEVELOPMENTAL SCREENING TOOLS
UPDATED 2026-2027 WITH 120 PRACTICE
QUESTIONS AND ANSWERS EXAMS
**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
**Answer: B**
*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
**Answer: C**
*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 AAP, at what ages should standardized
developmental screening be performed?**
- A) 6 months, 12 months, and 24 months
- B) 9 months, 18 months, and 30 months
- C) Birth, 6 months, and 12 months
,- D) Annually from birth to age 5
**Answer: B**
*Rationale:* The American Academy of Pediatrics (AAP) recommends
standardized developmental screening at 9, 18, and 30 months of
age. Additionally, screening should be performed whenever a
clinician's surveillance "demonstrates risk." Despite these
recommendations, many practices do not routinely screen all young
patients or consistently refer children who are identified as needing
follow-up .
---
**4. Which of the following statements about universal and periodic
screening is TRUE?**
- A) Screening is only necessary for children from low socioeconomic
backgrounds
- B) Children with typical screening results do not need repeated
screening
- C) Universal and periodic screening of all children from birth to age
5 is critical
- D) Children from culturally diverse families can be exempted due to
language differences
**Answer: C**
, *Rationale:* Universal and periodic early identification of all young
children is critical because development is dynamic, and problems
can arise at any time during the early years. Without periodic
screening, timely identification is not possible, and problems may
evolve into more serious threats to well-being. Risk factors alone
cannot reliably predict which children will experience developmental
delays .

**5. What percentage of children from birth to 21 years are
diagnosed with a developmental-behavioral disorder or disability in
the United States?**
- A) 5-7%
- B) 10-12%
- C) 15-17%
- D) 25-30%
**Answer: C**
*Rationale:* Historical and contemporary research consistently
suggests that approximately 15-17% of children from birth to 21
years are diagnosed with a developmental-behavioral disorder or
disability. This includes conditions such as speech/language
impairment (13.5% expressive speech delays at 18-23 months),
ADHD (7.6%), learning disabilities (7.2%), and autism spectrum
disorder (0.74-1.1%) .
