The Stanford-Binet Intelligence Scales, Fifth Edition is a broad-age cognitive measure with verbal and nonverbal routing and five factor areas. It is often selected for gifted identification, developmental questions, intellectual-disability evaluation, or cases where a broad floor and ceiling are useful.

Last Updated: August 2026

History of the Stanford-Binet

The test traces its roots to Alfred Binet and Théodore Simon’s early twentieth-century work in France. Lewis Terman adapted the scale at Stanford University in 1916, and later revisions modernized norms and theory. The Fifth Edition, published in 2003, uses a hierarchical model with verbal and nonverbal measurement.

Five Cognitive Factors

Scores and Routing

The SB-5 uses routing subtests to estimate an appropriate starting level and reduce unnecessary items. It can produce Full Scale IQ, Verbal IQ, Nonverbal IQ, factor indexes, and subtest scores. Interpretation should consider confidence intervals and the consistency of the profile.

Stanford-Binet Compared With Other Tests

Why a Psychologist May Choose SB-5

• Very broad age range and continuity across development.
• High ceiling useful in some gifted-identification cases.
• Verbal and nonverbal routes that may help explore language-related differences.
• Quantitative reasoning as a distinct factor.
• Strong floor for some developmental and intellectual-disability questions.

When Another Test May Be Better

• WISC-V may align more directly with common school-age referral practices.
• WAIS may be preferred for adult clinical, disability, and neuropsychological contexts.
• A full evaluation may be required when the question involves achievement, attention, autism, emotional functioning, or adaptive behavior.
• The receiving program may explicitly require a different instrument.

IQ, Gender, Language, and Demographic Context

Professional intelligence tests use national age-based norms rather than a separate Henderson norm for women, men, racial groups, ethnic groups, neighborhoods, or school systems. Overall intelligence distributions overlap substantially by sex. Individual people can still show meaningful differences among verbal comprehension, visual-spatial reasoning, fluid reasoning, working memory, quantitative reasoning, and processing speed.

Current Census context for Henderson test-takers:

• Female residents: 50.6% of the population.
• Female civilian labor-force participation: 56.7% among residents age 16 and older in 2020–2024.
• Residents under age 18: 20.8%; residents age 65 and older: 20.8%.
• White alone: 61.7%; Black alone: 6.9%; Asian alone: 9.8%; American Indian and Alaska Native alone: 0.9%; Native Hawaiian and Other Pacific Islander alone: 0.6%; two or more races: 14.0%.
• Hispanic or Latino residents: 18.1%; Hispanic origin may overlap with race categories.
• Foreign-born residents: 14.3%.
• Language other than English spoken at home: 19.0% of residents age 5 and older.
• High-school graduate or higher: 93.6% of adults age 25 and older; bachelor’s degree or higher: 37.4%.

No authoritative public dataset establishes valid citywide IQ averages by gender, race, ethnicity, school, ZIP code, or neighborhood. A psychologist should interpret results in light of age, education, language, culture, disability, health, sleep, medication, effort, sensory needs, and testing conditions rather than assigning ability from demographic membership.

Stanford-Binet Use in Henderson

Local families may consider SB-5 for giftedness, private-school planning, developmental evaluation, or broad-age assessment. Adults may use it for clinical questions or accepted prior evidence where the complete report meets organizational requirements. There is no public citywide database of SB-5 scores or usage volume.

Henderson Universities, Training Centers, and Health Institutions

• Nevada State University: A public four-year institution in Henderson offering undergraduate and graduate pathways, including education, nursing, business, psychology-related study, and interdisciplinary programs.
• College of Southern Nevada: The Henderson Campus at 700 College Drive offers general education and specialized programs, while the Green Valley Center and Debra March Center of Excellence expand access to technology, workforce, and advanced-manufacturing training.
• Touro University Nevada: A Henderson graduate and professional campus focused on osteopathic medicine, physician-assistant studies, nursing, occupational therapy, physical therapy, medical health sciences, and education.
• Roseman University of Health Sciences: The Henderson campus supports health-professions education, including pharmacy, nursing, dental medicine, biomedical science, and related graduate preparation.
• Nearby UNLV and Desert Research Institute: Las Vegas institutions add research, graduate education, disability services, continuing education, and specialist referral networks within the broader valley.
• Hospitals and clinical systems: Dignity Health–St. Rose Dominican campuses, Henderson Hospital, West Henderson Hospital, outpatient centers, pediatric practices, behavioral-health providers, and private psychology practices serve the area.

University or hospital affiliation does not automatically mean a clinic offers stand-alone IQ testing to the public. Confirm age range, referral criteria, insurance requirements, waitlist, report type, language services, and whether the evaluation answers the receiving institution’s question.

Access Patterns Across Henderson

There is no authoritative neighborhood-level IQ database, and responsible clinicians do not assign estimated scores to communities. The areas below are included only to explain transportation, school, institutional, and appointment-access patterns relevant to Stanford-Binet testing.

• Water Street District and Townsite: The historic civic core near City Hall, community facilities, older neighborhoods, local schools, and the Water Street corridor.
• Green Valley and Whitney Ranch: Established residential and commercial areas with schools, medical offices, retail centers, and access to I-215, Sunset Road, Stephanie Street, and Green Valley Parkway.
• Anthem, Seven Hills, MacDonald Ranch, and Inspirada: South and southwest master-planned communities with growing families, schools, parks, and access through Eastern Avenue, St. Rose Parkway, Volunteer Boulevard, and Via Inspirada.
• Cadence and Lake Las Vegas: Eastern growth areas near Lake Mead Parkway, Nevada State University, trail systems, and routes toward Boulder City and Lake Mead.
• West Henderson: A rapidly developing employment and residential area near Henderson Executive Airport, the Debra March Center of Excellence, industrial development, and I-15/I-215 connections.
• Black Mountain, Mission Hills, and Paradise Hills: Southeastern neighborhoods with access to College Drive, US-93/US-95/I-11, CSN Henderson, Nevada State University, and outdoor recreation corridors.

Transportation and Appointment Access

• Major roads: I-11/US-93/US-95 through the eastern valley; I-215 and Clark County 215 across Green Valley and west Henderson; Lake Mead Parkway/SR-564; Boulder Highway/SR-582; St. Rose Parkway/SR-146; Eastern Avenue; Stephanie Street; Green Valley Parkway; and Volunteer Boulevard.
• Public transit: The Regional Transportation Commission of Southern Nevada operates fixed-route bus service connecting Henderson with Las Vegas and Boulder City. Current routes and timetables should be checked before an appointment. RTC OnDemand also serves parts of west Henderson and the southwest valley.
• Airports: Harry Reid International Airport (LAS) provides commercial air service for the region. Henderson Executive Airport (HND) is a general-aviation and business-aviation facility in west Henderson.
• Distance to other places: Many Henderson locations are roughly 15–30 minutes from the Las Vegas Strip, 20–35 minutes from downtown Las Vegas, 15–25 minutes from Boulder City, 30–45 minutes from Hoover Dam, about 1.5 hours from Laughlin or Mesquite, and roughly 4–5 hours by road from Los Angeles or Phoenix, depending on traffic and starting point.
• Walkability: Most of the city is suburban and car-oriented. The Water Street District and The District at Green Valley Ranch offer the most concentrated walkable clusters of shops, dining, civic uses, and services; some master-planned areas include connected paths but still require driving for many appointments.
• Bike infrastructure: Henderson reports more than 300 miles of trails. Major facilities include the River Mountains Loop Trail, Harry Reid Union Pacific Railroad Trail, Pittman Wash Trail, Amargosa Trail, neighborhood paths, on-street bicycle facilities, and links toward Lake Mead and Boulder City.
• Practical scheduling: Ask about parking, elevator access, sensory environment, restroom access, public-transit proximity, testing-room temperature, breaks, and whether multi-session evaluations can be scheduled at times that reduce fatigue and traffic exposure.

Administration and Reporting

Testing time often ranges from roughly 45 to 90 minutes for the core cognitive battery, but age, ability, breaks, rapport, supplemental measures, and clinical complexity can lengthen the appointment. A report should explain routing, factor scores, confidence intervals, behavior, limitations, and recommendations.

Verbal, Nonverbal, and Routing Structure

The Stanford-Binet 5 uses routing subtests to estimate an appropriate starting level and then samples five cognitive factors in verbal and nonverbal formats. This structure can provide more than a single Full Scale IQ. Depending on the referral question and score pattern, a psychologist may discuss Verbal IQ, Nonverbal IQ, factor index scores, subtest-level observations, confidence intervals, and whether the global score adequately summarizes the examinee’s functioning.

• Fluid reasoning: Solving novel problems and identifying relationships without relying only on previously learned information.
• Knowledge: Acquired information, vocabulary, and concepts shaped by education, experience, language, and opportunity.
• Quantitative reasoning: Understanding numerical relationships and solving age-appropriate mathematical reasoning tasks.
• Visual-spatial processing: Analyzing patterns, forms, positions, and spatial relationships.
• Working memory: Holding and mentally manipulating information over a short period.

The verbal/nonverbal distinction does not make the assessment culture-free or language-free. Instructions, familiarity with testing, educational experience, sensory or motor needs, attention, fatigue, anxiety, and rapport can affect performance. Henderson’s multilingual and internationally mobile population makes it especially important to discuss language history, schooling, disability accommodations, and the intended use of results before selecting the test.

For very young children, highly gifted examinees, people with uneven profiles, or individuals whose motor or language needs complicate other instruments, the SB-5 may offer useful flexibility. That does not mean it is automatically the best choice. The psychologist should explain why SB-5 fits the age, referral question, receiving institution, and required documentation better than WISC-V, WAIS-IV/WAIS-5, an achievement test, or a broader neuropsychological battery.
