This first experiment was performed as part of the process of developing a standardized performance criterion for journeyman enroute traffic controllers. The final performance measurement system will be used in personnel research such as evaluating potential aptitude test capacity to predict suitability for entrance into training. The criterion measure will be based on the use of realistic dynamic simulation of the radar air traffic control situation. The completed measurement system will be required to possess reliability, objectivity, and relevance of measurement of performance. Another requirement will be the availability of alternate traffic problems which are different but proven to be of equivalent difficulty level. This experiment sought directions for constructing different but equally difficult parallel forms of the test by using combinations of sector geographic structures and traffic density levels. Two sectors, which differed widely in geographic structure, and three traffic density levels were orthogonally combined to yield six experimental conditions. Six experienced air traffic controllers worked under each of the six conditions in the ATC simulator. Results indicated that performance scores were much less affected by sector structure than by traffic density. Consequently, it was accepted as a guideline for further work that parallel forms can be built on the basis of traffic density level equivalence alone.
