The aim of this research was to identify the factors that could be used for quality assessments of the placement centres used by the University of Barcelona's Faculty of Education. To achieve this, a multiple case study method (bachelor's degrees in Education, Social Education and Social Work) was used, which was based on a survey methodology. A questionnaire, which identified seven quality criteria, was applied to 291 placement centres. An analysis of the placement centres' average quality scores revealed that most of them had high scores for consideration of the training activity, tutor-student ratio, type of placement, capacity of providing career opportunities, the centre's tutoring, the tutors' tasks and the coverage of the competences. We considered it necessary to improve the definition of quality placement plans, and the recognition of the tutor's work at the centre; therefore, this paper proposes an instrument to measure and assess the quality indicators described, aiming at improving the placements system at the University by better connecting universities and centres.
