Science: The fundamental rationale for the tenure system has been to promote the long-term development of new ideas and to challenge students’ thinking says Dan Clawson from the University of Massachussetts Amherst, Amherst, MA. Proponents argued more than 60 years ago that tenure is needed to provide faculty the freedom to pursue long-term risky research agendas and to challenge conventional wisdom. Those arguments are still being made today and are still valid.However, a 30-year trend toward privatization is creating a pseudoâmarket environment within public universities that marginalizes the tenure system. A pseudoâmarket environment is one in which no actual market is possible, but market-like mechanisms (such as benchmarking and rankings based on research dollars, student evaluations, or similar attributes) are used to approximate a market.
