Who made the standardized test?

Standardized tests have a varied history with contributions from multiple individuals and organizations. One of the earliest standardized tests in the U.S. was developed by Alfred Binet and Théodore Simon in the early 20th century to assess intelligence in children. Later, organizations like the Educational Testing Service (ETS) and companies like Pearson played significant roles in creating and administering standardized tests such as the SAT and ACT. These tests have evolved over time, influenced by educational policies and research in assessment.
