The pandemic situation at the beginning of March 2020 forced teachers to develop alternative teaching methods, and most important to find the best ways to keep teaching for every student no matter the situation, as for example, the lack of computer knowledge or hardware/software support. Teachers worldwide struggled to support, encourage, find the best ways not only to help students to keep learning but support them emotionally. At the end of the academic year, teachers made efforts to develop fair, appropriate evaluation procedures adapted to distance education. This paper summarizes the Distance Teaching-Learning-Evaluation (DTLE) evolution in Russia and Romania and some methods developed from March to December 2020 to support the educational activity. Some benefits, challenges and difficulties are identified during the same period of time in different DTLE scenarios, from the point of view of teachers and students, as well. Examples of new adapted methods, dedicated to the DTLE scenarios are al-so addressed in this work.
