The California and Western Conference Cost and Statistical Study records range in date from 1950-1961 with the bulk of the material coming from the years 1954-1955. The collection is organized into four series; Administrative files; Reports; Data; and Forms. The series Administrative files is further organized into three sub-series: General study information; Financial files; and Correspondence. The Reports series is divided into two sub-series: Informal and Formal. The oversized material in the collection is listed where it would fall organizationally but is physically located in box 6.

The first series is Administrative files. It contains materials dating from 1953-1961. It is organized into three sub-series. The first sub-series is General study information. This sub-series spans the years 1953-1961 and includes informal reports, some correspondence, and a small amount of data all having to do with the overall perception and aim of the study. The second sub-series consists of material from the years 1953-1957 and is entitled Financial files. As the title suggests it contains information about expenditures during the study. The third sub-series is correspondence. The letters in this sub-series come from the years 1953-1958. While the bulk of the correspondence can be found in the folder labeled Big Ten/ California correspondence, there are four files with individual names. These individuals are professionals hired by the institutions to do various aspects of research and/or calculations.

The second series is Reports. This series spans the years 1950-1961. It is divided into two sub-series; Informal and Formal. The first sub-series, Informal, consists of records dating from the years 1953-1961. This series includes minutes and informal reports, such as memos or notes that were made by the committee. Formal, the second sub-series, contains typed reports produced by the committee that address different aspects of the project. It spans the years 1950-1957. It also includes a number of plastic bound final reports that were given to institutions upon completion of the study. The reports of the California and Western Conference Cost and Statistical Study contain data from the years 1954-1955. However, they are labeled undated since the publication date itself is missing. The bound reports also include reports about the medical schools of the institutions.

The third series covers the years 1953-1957. The title of this series is Data and contains lists and tabulations of data created in the study not governed by a standard form established by the committee. The folder entitled "C&WCCSS multiple layout forms/forms for electronic accounting machine cards" consists of photocopies of oversized reports, which were Photostat copies themselves. After being photocopied, the original oversized materials were then discarded. The bulk of the raw data has to do with Indiana or Purdue University.

The last series, Forms, spans the years 1953-1956. This series consists of the blank and completed forms created by the committee. Many of these forms were originally bound in cardboard and metal binders, while others are photocopies of the originals which were oversized. The duplicates of blank forms and their instructions were discarded.
