Evidence-based practice (EBP)

A decision-making approach that combines the best available research evidence, the clinician's expertise, and the client's values, preferences, and circumstances when choosing assessment or treatment procedures.

Related: Clinical practice guideline, Informed consent, Treatment fidelity
ASHA Code of Ethics

The professional code binding certified speech-language pathologists, organized around core principles such as responsibility to clients, competence, and integrity, with enforceable rules governing clinical and professional conduct.

Related: Scope of practice, Informed consent, Mandated reporting
Scope of practice

The range of professional activities a clinician is legally and ethically permitted to perform, defined by state licensure law and professional documents; services outside it require referral or supervision.

Related: ASHA Code of Ethics, Clinical fellowship, Supervision
Informed consent

Obtaining a client's or surrogate's voluntary agreement to evaluation or treatment after explaining purpose, procedures, risks, benefits, alternatives, and the right to withdraw at any time.

Related: ASHA Code of Ethics, Confidentiality (HIPAA/FERPA), Evidence-based practice (EBP)
Confidentiality (HIPAA/FERPA)

The legal and ethical duty to protect client records and communications; HIPAA governs health information in most settings, while FERPA protects education records and requires consent for most disclosures.

Related: Informed consent, Mandated reporting
Mandated reporting

The legal obligation of clinicians to report suspected child abuse, neglect, or abuse of vulnerable adults to designated authorities, even when the information was learned during confidential clinical services.

Related: Confidentiality (HIPAA/FERPA), ASHA Code of Ethics
Clinical practice guideline

A systematically developed statement that helps clinicians and clients make decisions about appropriate care for specific clinical circumstances; it informs but does not replace individualized clinical judgment.

Related: Evidence-based practice (EBP), Treatment fidelity
Treatment fidelity

The degree to which an intervention is delivered as designed and intended, including adherence to procedures, dosage, and quality of delivery; low fidelity weakens conclusions about treatment effectiveness.

Related: Evidence-based practice (EBP), Dosage (treatment intensity)
Supervision

The oversight a qualified clinician provides to students, clinical fellows, assistants, or less experienced staff, including observation, feedback, and shared accountability for client care and documentation.

Related: Scope of practice, Clinical fellowship
Clinical fellowship (CF)

The supervised post-master's period of professional practice required for ASHA certification, during which a fellow completes mentored clinical work and is evaluated by an ASHA-certified supervisor.

Related: Supervision, Scope of practice
Standardized test

An assessment with fixed administration and scoring procedures and normative data, allowing a client's performance to be compared with a representative reference group using standard scores and percentiles.

Related: Standard score, Norm-referenced assessment, Ceiling and basal rules
Norm-referenced assessment

Measurement in which a client's score is interpreted relative to the distribution of scores from a normative sample, indicating how far performance deviates from typical peers.

Related: Standardized test, Standard score, Percentile rank
Criterion-referenced assessment

Measurement that compares a client's performance to a defined standard or skill criterion rather than to other people, showing what the client can and cannot do.

Related: Dynamic assessment, Curriculum-based measurement
Standard score

A transformed score expressing how far a raw score lies from the normative mean in standard deviation units; common scales use a mean of 100 and standard deviation of 15.

Related: Standardized test, Percentile rank, Standard error of measurement
Percentile rank

The percentage of individuals in the normative sample who scored at or below a given raw score; a percentile of 25 means the client performed as well as or better than 25 percent of peers.

Related: Standard score, Norm-referenced assessment
Standard error of measurement (SEM)

An index of the average amount of error in a test score, used to build confidence intervals around an observed score and to judge whether score differences are meaningful.

Related: Standard score, Reliability, Validity
Reliability

The consistency or dependability of a measurement across items, occasions, or raters; a test cannot be valid if it is unreliable, though reliability alone does not guarantee validity.

Related: Validity, Standard error of measurement (SEM)
Validity

The extent to which a test measures what it claims to measure and supports the intended interpretations and decisions, including content, construct, and criterion-related evidence.

Related: Reliability, Sensitivity and specificity
Sensitivity and specificity

Sensitivity is the proportion of people with a disorder correctly identified by a screening or diagnostic measure; specificity is the proportion without the disorder correctly identified as unaffected.

Related: Screening, Validity, Positive predictive value
Positive predictive value

The probability that a person who tests positive on a screening or diagnostic measure actually has the disorder, which depends on sensitivity, specificity, and the base rate in the population.

Related: Sensitivity and specificity, Screening
Screening

A brief, low-cost procedure used to identify individuals who may need further evaluation; screening does not diagnose and typically requires follow-up assessment for confirmation.

Related: Sensitivity and specificity, Dynamic assessment
Dynamic assessment

An interactive assessment approach that measures a learner's ability to improve with mediation, cues, or teaching, often distinguishing language difference from language disorder.

Related: Criterion-referenced assessment, Language difference versus disorder
Ceiling and basal rules

Test administration rules that determine starting and stopping points: a basal is the point below which items are credited as correct, and a ceiling is the point at which testing stops.

Related: Standardized test, Standard score
Language difference versus disorder

A difference reflects normal variation such as dialect or second-language influence, whereas a disorder is a deficit relative to the person's own language community and is not explained by cultural or linguistic diversity.

Related: Dynamic assessment, Bilingual assessment, Accent modification
Bilingual assessment

Evaluation of a multilingual client that considers both languages, uses appropriate tools and interpreters, and distinguishes typical second-language acquisition patterns from true impairment.

Related: Language difference versus disorder, Dynamic assessment
Curriculum-based measurement
