The Organizational Health Instrument (OHI) consists of 80 statements, eight for each of the ten dimensions. All members of a work unit respond to these questions and data collection procedures are established and followed that preserve the integrity of the data.

Response choices are: Strongly Agree, Agree, Undecided, Disagree, and Strongly Disagree. Based upon these collective responses, raw scores are established for each of these ten dimensions. The raw scores are converted into percentile scores. 

With a national data base that spans three decades, OHDDC has established group norms for key leadership groups throughout the public and private sectors. For example, in the public school sector, group norms have been established for Elementary Schools, Middle Schools, Junior High Schools, Senior High Schools, Alternative Schools, Central Office Administrative Units, Superintendents, Policy Teams, Non-certified units, and School Community (parents' perception).
