Scholastic Testing Service, Inc. is a close-knit, privately-held company. We consider our customers to be members of our extended family, and we are grateful for their continued patronage. If you are new to STS, we cordially invite you to become part of our family. Our company history is included below to help you become more familiar with us.

Our history began in 1952 with a fortuitous conversation between Mathematics Professor Oliver F. Anderhalter and Loyola University Press Sales Manager Herbert J. Greig. The two men met at a St. Louis University workshop hosted by Dr. Anderhalter. During the workshop, Dr. Anderhalter asked Mr. Greig how well students were learning from the textbook series used at the workshop. Mr. Greig replied that he had no idea because there was no test to assess the success of the series. Dr. Anderhalter proposed developing a test for the series, which Mr. Greig would market. The two men agreed on the concept and Scholastic Testing Service was born. Mr. Greig rented a small room from the University of Chicago to serve as our first office, and the company was incorporated in Illinois in 1953.

Dr. Anderhalter and Mr. Greig worked in concert to develop our very first tests. Mr. Greig brought textbooks, lesson plans, and teacher curriculum notes to Dr. Anderhalter and a group of graduate students, who used these materials to create a series of questions. These first tests were criterion referenced and developed around the curriculum of particular school districts. They were then marketed to superintendents to help assess teacher accountability for the textbook series.

Although Scholastic Testing Service, Inc. produced customized tests for particular school districts, we did not have a standardized test battery. The first STS standardized test was the High School Placement Test (HSPT®), which was developed and published in 1955. At the time, private schools were very desirable and private school administrators needed a test to help them determine admissions, scholarships, and academic placement. The HSPT® fulfilled these needs.

Next, in the line of standardized test batteries came the Educational Development Series (EDSeries) used for evaluating eight subjects in junior high schools. During the early 1960s, the EDSeries was further developed and soon covered kindergarten through grade 12.

As STS tests became more widely used, test authors and other publishers began to send instruments to us for publication. Our current catalog reflects the many selections that we have published during the past decades.

The range of our products continues to evolve to meet the needs of our customers. Each year we develop new forms for the High School Placement Test (HSPT®), and we recently developed new forms (G & H) for the QUIC™ tests. This year we are also introducing the Kindergarten Readiness Test (KRT). The KRT assesses young children’s readiness for kindergarten and is an extension of STS’ School Readiness Test (SRT), which assesses student readiness for first grade.

The KRT is available now for purchase. The newly revised QUIC™ tests are now available for customer use. The KRT, SRT and QUIC™ are available for online purchase to qualified users.
