Introduction: In the information society, the stimulus threshold for learners has changed, which requires a novel education strategy. Today, it is no longer what attracts students’ attention that it was 20 years ago. In addition to the rapid development of ICT, public education cannot go either. We believe that advanced teacher digital competence can be one of the keys of finding common ground with students and doing effective teaching work. Methods: In our research we examine the level of digital competence of public education teachers before the pandemic and during the 2nd wave in Hungary (2020 autumn). We examine the development of digital competence, student performance, and the effectiveness of education outside the classroom in the spring period based on teacher experience. Data from the completed forms were evaluated by using basic statistical indicators. Results: According to the data received, the pandemic revealed serious shortcomings in the level of development of the digital competence of both teachers and students. However, it also opened the way for catching up on both sides. Teachers were already better prepared during the second wave, so they were able to solve education more efficiently. Regional development differences and a lack of digital tools have widened the gap between students. Discussion: The COVID-19 pandemic has exposed these shortcomings in education. For here the process of teaching had to be placed in digital space from one moment to the next. Limitations: The research shows data valid only for Hungary. Conclusions: Expected result is the demonstrable development of competences.
