The Covid-19 has closed the whole world including the schools and colleges. This situation never thought before this in the world. Over billions of K-12 students are out of educational institutions due to this novel virus. We cannot put this risk into the future of students. Therefore, this study was conducted to explore the latest trends and practices of educational institutions which are useful during and after the Covid-19. The investigation was a mixed method (quantitative and qualitative) study which focused on questionnaires and interviews of the participants for the data gathering. A sample of 170 respondents in which 10 heads of secondary schools, 10 university professors, 50 K-12 teachers and 100 K-12 students were selected for the collection of quantitative data. However, the sample size in the collection of qualitative data was not fixed. The data collection was stopped when the emerging of new data themes stopped and the final sample of qualitative data collection was 23 participants. The triangulation technique was used to cross check the results and validation of data. The study found that the online education properly planned by the administration in the modern K-12 education in the world is the best solution during the Covid-19.
