Industry History
The history of the Psychometric Services industry dates back to the early 20th century when the first intelligence tests were developed by Alfred Binet and Theodore Simon in France. These tests were used to measure cognitive abilities and were later adapted for use in the United States by Lewis Terman. In the 1940s, the industry saw a significant increase in demand due to the need for psychological testing during World War II. The industry continued to grow in the following decades, with advancements in technology leading to the development of computerized testing and online assessments. In recent years, the industry has seen a shift towards more personalized and adaptive testing, as well as an increased focus on emotional intelligence and personality assessments.
In the United States, the Psychometric Services industry has a relatively short history, with the first standardized intelligence tests being developed in the early 1900s. The industry saw significant growth in the mid-20th century, with the development of the Graduate Record Examination (GRE) and the Scholastic Aptitude Test (SAT). In the 1980s and 1990s, the industry saw a shift towards computerized testing and online assessments, with the development of the first computerized adaptive testing systems. In recent years, the industry has continued to evolve, with a focus on developing more accurate and reliable assessments, as well as a growing interest in the use of artificial intelligence and machine learning in testing and assessment.

About this classification
This page represents a commercial Extended NAICS industry classification used for business targeting, industry research, data analysis, and company classification. It is not an official U.S. Census Bureau NAICS code. Its parent industry is an official NAICS classification defined by the U.S. Census Bureau. Classifications are reviewed regularly by SICCODE.com's Classification Review Team.
SICCODE.com classifies companies under both Extended NAICS and Extended SIC. A company may appear in both classification systems, so company counts should not be added together without deduplication.
