Nationally Certified Educational Diagnostician (NCED) — Questions and Answers

Question 1: A diagnostician concludes that a student does not meet eligibility criteria for special education. The evaluation report must still:

Be destroyed within 60 days to protect student privacy
Document the data sources, findings, and basis for the eligibility decision (Correct answer)
Recommend private services as an alternative
Be shared only with the student's classroom teacher

Correct answer: Document the data sources, findings, and basis for the eligibility decision

Regardless of eligibility outcome, the evaluation report must document the assessment data, methods, and the team's rationale so that the decision is transparent and defensible.

Question 2: A student with an IEP transitions from elementary to middle school. Which action is legally required?

The receiving school must have an IEP in effect on the first day of school (Correct answer)
The IEP must be rewritten by the new team before transfer
A completely new evaluation must be conducted
Parents must re-consent to all services

Correct answer: The receiving school must have an IEP in effect on the first day of school

IDEA requires that a student with a disability have an IEP in effect at the beginning of each school year, including when transferring between schools.

Question 3: Which NEC article specifically governs branch circuits?

Article 210 (Correct answer)
Article 310
Article 230
Article 250

Correct answer: Article 210

NEC Article 210 covers branch circuits, including ratings, required outlets, and the rules for various room types.

Question 4: How should an educational diagnostician handle situations involving a student who has a disability and exhibits behavioral challenges?

By collaborating with other professionals to develop supportive and non-punitive interventions. (Correct answer)
By focusing only on the academic performance and ignoring the behavioral aspects.
By applying punitive measures to correct the behavior.
By reporting the behavior to the school administration without further action.

Correct answer: By collaborating with other professionals to develop supportive and non-punitive interventions.

When a student with a disability exhibits behavioral challenges, an educational diagnostician should collaborate with a multidisciplinary team, including psychologists, social workers, and teachers, to develop supportive and non-punitive interventions. This approach recognizes that behavior can be a form of communication or a symptom of an underlying need related to the disability. The goal is to understand the function of the behavior and implement positive behavior supports rather than simply punishing the student.

Question 5: Which law ensures that educational diagnosticians maintain confidentiality of student records?

FERPA (Family Educational Rights and Privacy Act). (Correct answer)
IDEA (Individuals with Disabilities Education Act).
ADA (Americans with Disabilities Act).
No Child Left Behind Act.

Correct answer: FERPA (Family Educational Rights and Privacy Act).

The Family Educational Rights and Privacy Act (FERPA) is a federal law that protects the privacy of student education records. It grants parents certain rights with respect to their children's education records and gives eligible students control over their own records. Educational diagnosticians, like all school officials, are legally bound by FERPA to maintain the confidentiality of student records and only disclose them with proper consent or under specific exceptions.

Question 6: An educational diagnostician reviews an IEP and notes that progress monitoring data is collected only at report card time. What is the primary concern?

Report card periods satisfy IDEA progress reporting requirements
Parents receive too much data
Infrequent monitoring cannot inform timely instructional adjustments (Correct answer)
Progress notes must be collected daily per IDEA

Correct answer: Infrequent monitoring cannot inform timely instructional adjustments

Effective progress monitoring requires frequent data collection so that instruction can be adjusted promptly when a student is not on track to meet annual goals.

Question 7: A student demonstrates strong performance on isolated phonics tasks but reads connected text slowly and with many errors. The diagnostician should prioritize assessing:

Visual acuity and tracking
Reading fluency and automaticity of decoding in context (Correct answer)
Advanced vocabulary and morphology
Listening comprehension and oral language

Correct answer: Reading fluency and automaticity of decoding in context

A gap between isolated phonics and connected text reading signals that decoding has not become automatic, implicating reading fluency as the key diagnostic target.

Question 8: A parent disagrees with the IEP team's proposed placement. Which procedural safeguard allows an independent review before litigation?

Mediation or due process hearing (Correct answer)
Extended school year request
Section 504 accommodation plan
Child Find complaint

Correct answer: Mediation or due process hearing

Parents may request mediation or a due process hearing to resolve disagreements about IEP decisions, including placement, before resorting to civil litigation.

Question 9: A hydraulic pump that produces excessive heat but normal pressure most likely has:

A blocked pump inlet strainer
A faulty pressure compensator
High internal leakage causing fluid to recirculate internally (Correct answer)
A worn pressure relief valve

Correct answer: High internal leakage causing fluid to recirculate internally

Internal pump leakage causes fluid to slip from high-pressure to low-pressure passages inside the pump, converting hydraulic energy to heat without doing useful work.

Question 10: Which document outlines the ethical obligations specific to educational diagnosticians certified by the National Association of Special Education Teachers (NASET) and related bodies?

NASDSE Policy Guidelines
APA Ethical Principles of Psychologists
CEC Code of Ethics for Special Educators (Correct answer)
FERPA Implementation Guide

Correct answer: CEC Code of Ethics for Special Educators

The Council for Exceptional Children (CEC) Code of Ethics provides the primary ethical framework governing the professional conduct of special educators, including educational diagnosticians.

Question 11: Which component is ESSENTIAL in a written evaluation report under IDEA?

The evaluator must include a minimum of five norm-referenced tests
A specific disability label must appear in the summary
The report must document whether the student was found eligible and the basis for that determination (Correct answer)
Recommendations must include a specific grade placement

Correct answer: The report must document whether the student was found eligible and the basis for that determination

IDEA requires that evaluation reports document eligibility determination and the data and rationale supporting that conclusion.

Question 12: When replacing a clutch disc on a rear-wheel drive vehicle, technicians should also inspect the:

Transfer case fluid and output seals
Flywheel or flexplate for wear, cracks, and heat spots (Correct answer)
Transmission output shaft bearing and rear seal only
Driveshaft center support bearing alignment

Correct answer: Flywheel or flexplate for wear, cracks, and heat spots

A worn clutch often glazes or damages the flywheel surface, which must be resurfaced or replaced to ensure the new clutch disc wears evenly.

Question 13: Which of the following is a legal requirement for educational diagnosticians when conducting an evaluation?

Evaluate students only during regular school hours.
Ensure that all assessments are non-discriminatory and valid for the intended purpose. (Correct answer)
Only use tests that have been developed by private companies.
Conduct evaluations based on personal experiences with the student.

Correct answer: Ensure that all assessments are non-discriminatory and valid for the intended purpose.

A fundamental legal requirement for educational diagnosticians, particularly under laws like IDEA, is to ensure that all assessments used in an evaluation are non-discriminatory and valid for their intended purpose. This means tests must be culturally and linguistically appropriate, administered by trained personnel, and accurately measure what they claim to measure. This ensures fair and accurate identification of student needs, preventing misclassification or denial of services.

Question 14: A Behavior Intervention Plan (BIP) must be based on which prerequisite document?

A standardized behavior rating scale score
A psychiatric evaluation
A teacher behavior log only
A functional behavioral assessment (FBA) (Correct answer)

Correct answer: A functional behavioral assessment (FBA)

A BIP must be grounded in an FBA that identifies the antecedents, behavior, consequences, and function maintaining the problem behavior.

Question 15: What does a flow control valve with a check valve bypass (meter-out configuration) control?

Speed of actuator extension only
Speed of actuator retraction only
The exhaust flow rate from the actuator (Correct answer)
Inlet pressure to the actuator

Correct answer: The exhaust flow rate from the actuator

A meter-out flow control restricts the exhaust flow leaving the actuator, controlling speed while maintaining back-pressure for load stability.

Question 16: Which grounding electrode is required by NEC when a building has metal water pipes?

A concrete-encased electrode only
A driven ground rod installed 8 ft deep
The metal underground water piping system (if at least 10 ft buried) (Correct answer)
A plate electrode buried 24 inches below grade

Correct answer: The metal underground water piping system (if at least 10 ft buried)

NEC 250.52 requires the metal underground water pipe as a grounding electrode when at least 10 feet of it is in direct contact with earth.

Question 17: When a computerized cognitive assessment calculates composite scores automatically, the diagnostician's role in verifying output BEST reflects which professional responsibility?

Cross-checking computed scores against manual calculations to detect software errors (Correct answer)
Ensuring the student completed all subtests in the required order
Verifying that the student's photograph matches school records
Confirming that the software license has not expired

Correct answer: Cross-checking computed scores against manual calculations to detect software errors

Manually verifying computed scores catches software errors or data entry mistakes that could lead to incorrect diagnoses or eligibility determinations.

Question 18: Under IDEA, how often must an IEP be reviewed at minimum?

Every 2 years
Every 3 years
Annually (Correct answer)
Every 6 months

Correct answer: Annually

IDEA requires that each student's IEP be reviewed at least once per year to assess progress and make necessary adjustments.

Question 19: Which IEP component specifically describes how the student's disability affects involvement in the general education curriculum?

Transition plan
Related services listing
Present levels of academic achievement and functional performance (PLAAFP) (Correct answer)
Annual goals section

Correct answer: Present levels of academic achievement and functional performance (PLAAFP)

The PLAAFP statement must explain how the disability affects the student's involvement and progress in the general education curriculum.

Question 20: When assessing the cognitive ability of a student whose primary language is Spanish, which approach is most appropriate?

Administer a standard English-language battery without modification
Include a nonverbal intelligence test to reduce linguistic demands on the assessment (Correct answer)
Estimate cognitive ability exclusively from academic achievement performance
Rely solely on tests developed and normed in Spanish-speaking countries

Correct answer: Include a nonverbal intelligence test to reduce linguistic demands on the assessment

Nonverbal cognitive measures minimize the influence of English language proficiency on test performance, providing a fairer estimate of cognitive ability for English language learners.

Question 21: A student's IEP includes a goal for math computation. The diagnostician recommends using a calculator as an accommodation. A teacher objects, saying it 'gives the answer away.' Which response is most accurate?

The teacher's judgment overrides the IEP team decision
If the goal targets problem-solving rather than computation fluency, a calculator is an appropriate access tool (Correct answer)
Accommodations require annual reapproval by the state education agency
Calculators may never be used during instruction for students with math disabilities

Correct answer: If the goal targets problem-solving rather than computation fluency, a calculator is an appropriate access tool

Whether a calculator is appropriate depends on the skill being assessed—it supports access to higher-order math without altering problem-solving standards when computation is not the instructional target.

Question 22: The 'creep' behavior of a vehicle with an automatic transmission at idle in Drive is caused by:

Mechanical drag in the planetary gear sets
A stuck shift solenoid keeping the transmission engaged at all speeds
Fluid coupling torque multiplication in the torque converter at low speeds (Correct answer)
Residual hydraulic pressure in the clutch packs

Correct answer: Fluid coupling torque multiplication in the torque converter at low speeds

At idle, the torque converter still transmits some torque through fluid coupling, causing slight forward movement unless the brakes resist it.

Question 23: What is multi-factor authentication in NCED security?

Requiring two or more verification factors for access (Correct answer)
Same password for multiple accounts
A firewall type
A data encryption method

Correct answer: Requiring two or more verification factors for access

MFA requires multiple verification factors (knowledge, possession, biometrics), significantly reducing unauthorized access.

Question 24: Which type of reliability is most critical to consider when re-evaluating a student with the same cognitive battery after a three-year interval?

Split-half reliability
Test-retest reliability (Correct answer)
Internal consistency reliability
Inter-rater reliability

Correct answer: Test-retest reliability

Test-retest reliability measures the stability of scores over time, which is essential for determining whether observed score changes in a re-evaluation reflect true differences or measurement error.

Question 25: An educational diagnostician shares a student's evaluation report with a graduate intern without obtaining parental consent. This most likely violates:

Section 504's grievance procedure requirements
FERPA's restrictions on disclosing education records (Correct answer)
IDEA's Child Find provision
The state's mandatory reporting statute

Correct answer: FERPA's restrictions on disclosing education records

FERPA restricts disclosure of personally identifiable information in education records to school officials with a legitimate educational interest; an intern's access requires appropriate authorization.

Question 26: When conducting an evaluation for a student who is an English Learner, IDEA requires that assessment materials:

Be administered only in English to ensure standardization
Be approved by the state bilingual education office before use
Include only nonverbal measures to avoid language bias
Be provided in the language and form most likely to yield accurate information about the student's abilities (Correct answer)

Correct answer: Be provided in the language and form most likely to yield accurate information about the student's abilities

IDEA mandates that evaluation materials be administered in the language and form most likely to provide accurate data on what the student knows and can do, not on language proficiency.

Question 27: A test's standard error of measurement (SEM) is used to:

Compare a student's score to the norm group
Construct a confidence interval around an obtained score (Correct answer)
Calculate the reliability coefficient
Determine whether a discrepancy is educationally significant

Correct answer: Construct a confidence interval around an obtained score

The SEM is used to build confidence intervals that reflect the range within which a student's true score likely falls.

Question 28: When is it appropriate for an educational diagnostician to share student assessment results with others?

Only when consent from the student or guardian has been obtained, and there is a legitimate educational need. (Correct answer)
Whenever a teacher asks for the information.
Whenever a school administrator requests the information.
If the student has been diagnosed with a disability.

Correct answer: Only when consent from the student or guardian has been obtained, and there is a legitimate educational need.

Educational diagnosticians must adhere strictly to confidentiality laws, primarily FERPA, when sharing student assessment results. Information can only be shared with explicit consent from the student (if eligible) or their guardian, and only with individuals who have a legitimate educational interest in the student. This ensures the student's privacy is protected while allowing necessary information to be shared with those directly involved in their education.

Question 29: A functional behavioral assessment (FBA) is completed and reveals that a student's disruptive behavior is maintained by peer attention. Which intervention would BEST address this function?

Implement a token economy unrelated to social interaction
Increase instructional difficulty to reduce boredom
Teach the student an appropriate way to gain peer attention (Correct answer)
Remove the student from all peer interactions

Correct answer: Teach the student an appropriate way to gain peer attention

Function-based interventions replace the problem behavior with a socially acceptable behavior that achieves the same function—in this case, gaining peer attention.

Question 30: Why is an intercooler used in forced induction engines?

To cool compressed intake air, increasing its density and reducing knock risk (Correct answer)
To reduce oil temperature by adding a secondary cooling circuit
To pre-heat fuel for better atomization at cold temperatures
To cool the turbocharger bearings with ambient air

Correct answer: To cool compressed intake air, increasing its density and reducing knock risk

Compressing air raises its temperature and reduces density; the intercooler cools the compressed charge, resulting in denser air, more oxygen per cylinder fill, and lower knock tendency.
