The Luxembourg Centre for Educational Testing (LUCET) seeks to determine if Luxembourg schools are achieving their educational goals. This research unit of the University of Luxembourg conducts standardized tests with thousands of students each year to objectively assess key skills, academic performance and teaching quality. The online assessment system for these tests is delivered on a SUSE Linux Enterprise Server (SLES) cluster. In conjunction with SUSE Manager and the SUSE Linux Enterprise High Availability Extension, LUCET achieves highly efficient, secure and reliable operation of this critical application. SUSE Linux Enterprise (SLE) Micro not only allows them to deploy edge solutions very efficiently but also provides the capability to roll out the assessment system as a mobile solution in schools.
