Spanish doctoral theses on the Programme for International Student Assessment (PISA): a bibliometric study

Doctoral theses are an indicator of research activity in universities. The present study aims to analyse the production of doctoral theses on the OECD's Programme for International Student Assessment (PISA) to identify the collaborative networks generated by the scientific production of their authors. For this purpose, a bibliometric analysis and of social networks of 135 doctoral thesis included in the TESEO database from 20 academic years (2001/2002 to 2020/2021) was carried out. The results show that interest in PISA has progressively increased at the university level, in many cases both in the production of one thesis as well as in the publication of scientific articles. It has also been shown how the information generated by PISA has led to various collaborative networks among researchers.
