J. C. Hosack

J. C. Hosack (full name unknown and biographical details scarce) was a figure prominent in the early development and administration of standardized testing in the United States, particularly during the mid-20th century. Hosack's work focused significantly on test construction, validation, and implementation, often within the context of large-scale educational assessments. While not as widely recognized as some of the pioneering psychometricians of the era, Hosack contributed meaningfully to the practical application of testing principles in schools and other institutions. Further research is needed to ascertain the precise nature and extent of Hosack's contributions, as readily available biographical information is limited.
