1. Introduction: How to 'produce' educational performance
In the education process, information is usually asymmetrically distributed between
principals and agents. As a consequence, agents may behave opportunistically unless they can
be held accountable. That is, they can get away with behaving in ways that advance their own
interest rather than the principals' interest without negative consequences for them. By
providing comparable performance information, external examinations ease the monitoring
problems inherent in these principal-agent relationships, which leads to an improvement in
the overall performance of the system. External exams align the incentives of the agents with
the goals of the system, so that they additionally make it more likely that schools act
according to the goals of the system if they are given autonomy. Therefore, there is a
complementarity between external examination and school autonomy: Managing educational
institutions by giving them autonomy is more beneficial in systems with external exams.
1.1 Motivation and background
The main motivation for caring about a high quality of the education system lies in its
positive impact for societal productivity and equality. The quality of the education learnt in
school leads to higher productivity of both individuals and economies at large (W63mann
2003a, 2003b). At the same time, high-quality education for all also contributes to a more
balanced income distribution in society (Gundlach et al. 2003; Nickell 2004). It is thus critical
from a political and economic perspective to determine how the quality of educational
performance may be improved.
Extensive empirical evidence suggests that this cannot be done merely by spending more
on education. In most cases, additional resources do not seem to improve student
performance either over time or in a cross-sectional comparison (cf. Gundlach et al. 2001;
Hanushek 2002, 2003; W613mann and West 2005). In contrast, an institutional structure of
the education system which sets appropriate incentives has been shown to be associated with
better student performance (W6d3mann 2003c, 2004).
Central or external exams have been identified as such a performance-promoting
institution  (Bishop  1997; W613mann   2003c). Instead   of leaving  the organization,
implementation and marking of the examination of educational performance to individual
teachers or schools, central exams are run by an external agency. The comparable
information on student performance generated in this way changes the information status in
the education system. External exams thus change the incentives affecting all those involved
t This paper draws heavily on W6fmann (2003e and 2005b). 1 would like to thank conference participants in
