The purpose of the study is to identify the level of well-being of students and their basic psychological needs, with the return to the onsite teaching system in the university, after the COVID-19 pandemic. We also want to analyse the association relationship between students' well-being and their basic psychological needs. The study was attended by a number of 112 students at the Pedagogy of primary and preschool education enrolled in the second year, in the forms of full-time and part-time education. The working tools were taken from previous studies carried out on the Romanian population to evaluate students' structure of psychological needs, their self-perceived state of physical health and their level of well-being. The results obtained show the existence of a state of well-being and health above the average level. At the same time, the highest average, with a high level, was obtained at the subscale of the students' need for affiliation, with the return to onsite teaching-learning activities. The conclusions of the correlational study support the results obtained in previous studies, regarding the role of basic psychological needs in maintaining well-being, but emphasize that after online learning activities, the need for affiliation and competence (not autonomy) is associated with well-being, with a moderate effect size.
