Introduction
This CAISS 2 Actual Exam resource for the 2026/2027 academic cycle reflects advanced certification standards for
autism intervention specialists. The CAISS Level 2 examination evaluates comprehensive knowledge and clinical
competency required for professionals working with individuals across the autism spectrum, including advanced
assessment techniques, evidence-based behavioral interventions, communication strategies, sensory integration, family
collaboration, and ethical practice. Successful completion of the CAISS 2 examination demonstrates mastery of
advanced autism intervention principles and readiness for specialized practice in clinical, educational, and community
settings serving individuals with autism spectrum disorder.
Answer Format
All questions must be presented in bold text for clear distinction and readability.
All correct answers must be presented in bold and green, followed by clearly defined, detailed, verified rationales
that reinforce evidence-based autism intervention principles, behavioral analysis techniques, communication
development strategies, ethical practice, and clinical judgment required for CAISS 2 certification success.

Advanced ASD Assessment & Diagnosis (Q1-Q21)
1. A 7-year-old child presents with suspected Autism Spectrum Disorder. The interdisciplinary team is
conducting an advanced diagnostic assessment. Which assessment tool is considered a "gold standard"
observational assessment for diagnosing ASD?
A. Childhood Autism Rating Scale (CARS-2)
B. Gilliam Autism Rating Scale (GARS-3)
C. Autism Diagnostic Observation Schedule, Second Edition (ADOS-2)
D. Social Responsiveness Scale (SRS-2)
Rationale: The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is widely recognized as a "gold
standard" semi-structured, standardized assessment of communication, social interaction, play, and restricted and
repetitive behaviors for individuals suspected of having autism spectrum disorder. It involves direct observation of
behavior in various contexts.
,2. A CAISS 2 specialist is part of a diagnostic team evaluating a 14-month-old infant for early signs of ASD.
Which developmental red flag is MOST indicative of a need for immediate comprehensive evaluation?
A. Does not consistently respond to their name when called.
B. Has limited vocabulary of 3-5 words.
C. Does not engage in reciprocal babbling or pointing to share attention.
D. Shows occasional repetitive hand movements when excited.
Rationale: Failure to engage in reciprocal social interaction, such as reciprocal babbling or pointing to share
attention (joint attention), is a critical early marker of potential ASD by 12-14 months.
3. During an ASD assessment, a 5-year-old child demonstrates excellent rote memory for facts about dinosaurs
but struggles significantly with imaginative play and understanding other children's emotions. This presentation
highlights a core diagnostic criterion related to:
A. Restricted, repetitive patterns of behavior, interests, or activities (RRBs).
C. Deficits in social-emotional reciprocity and nonverbal communicative behaviors.
B. Impairment in adaptive functioning.
D. Challenges in sensory processing.
Rationale: Deficits in social-emotional reciprocity and nonverbal communicative behaviors are core diagnostic
criteria for ASD according to the DSM-5.
4. A CAISS 2 specialist is evaluating a non-speaking 4-year-old child. To accurately assess the child's
communication skills and social engagement, which approach should be prioritized over standardized
questionnaires?
A. Parent report of language milestones.
B. Direct observation in a highly structured clinical setting.
C. Naturalistic observation of interaction with familiar caregivers and peers across multiple settings.
D. Use of a augmentative and alternative communication (AAC) device to prompt responses.
Rationale: Naturalistic observation provides the most ecologically valid and comprehensive understanding of a non-
speaking child's communication and social skills.
, 5. A 10-year-old with a confirmed ASD diagnosis is undergoing re-evaluation. The CAISS 2 specialist notes that
the child exhibits self-stimulatory behaviors (stimming) more frequently when introduced to new, noisy
environments. This observation suggests the need to assess:
A. Cognitive flexibility.
C. Sensory processing challenges and their impact on self-regulation.
B. Executive functioning deficits.
D. Underlying anxiety and its social manifestations.
Rationale: Increased stimming in response to sensory triggers points directly to sensory processing and self-
regulation strategies.
6. When using the Autism Diagnostic Interview-Revised (ADI-R), what primary area is assessed through detailed
retrospective questioning of the caregiver regarding the individual’s developmental history?
A. Current adaptive skill levels.
B. Prognosis for independent living.
C. Quality and quantity of social reciprocity, language/communication, and restricted/repetitive behaviors prior to age 3
(or current level).
D. School performance in mathematics and science.
Rationale: The ADI-R is a semi-structured interview that relies on caregiver interview about past and current
behaviors, focusing heavily on the developmental history concerning core ASD domains.
7. A CAISS 2 specialist is administering the ADOS-2 Module 3 to a child who primarily uses single words. The
specialist observes the child uses a pointing gesture combined with an eye gaze toward a desired toy when the
facilitator only offers an inappropriate alternative. This interaction should be scored as evidence of:
A. A lack of expressive language capacity.
B. Complete absence of joint attention.
C. Functional communication attempting to direct attention/action.
D. Sensory regulation behavior.
Rationale: Pointing combined with eye gaze is a socially communicative act (a request or directive) even if not fully
verbal, demonstrating functional communication related to social goals.
