Overview: On line, learning has always been a debatable topic, yet during COVID-19. The students have no choice to choose online or traditional learning. Ministry of education has forced all students in Saudi Arabia to study through blackboard as a digital platform to protect them from COVID-19. The outcome of online learning has not been investigated as well as student's readiness, acceptance and environmental infrastructure. Aim: identify nursing student's perceived barriers, achievement and satisfaction to blackboard utilization as a digital platform. Design: exploratory descriptive research design was used. Setting: college of applied medical science, affiliated to Jouf University. Tools: four tools were used, 1-Nursing student's socio demographic characteristics, 2-Nursing students perceived achievements to black board digital platform, 3-Nursing Students perceived satisfaction to blackboard digital platform, 4-Nursing student's perceived barriers to blackboard digital platform. Result: blackboard was found to be unfamiliar way by more than half of the students (56.41). However, the finding conveyed that students with high computer experience had few obstacles to learn than those students with no computer experience, there were positive correlations with high statistical significant between all of sub-scales of black board perception regards perceived achievements, satisfaction and barriers. Conclusions: the study highlights nursing student's perceived barriers (hard method), need training, make students psychological disturbed. Moreover, it facilitates student's contribution & frustrates them to improve learning skills.

Background:The application of the WHO multimodal strategy during the periods of the outbreak of COVID-19, is of great importance for improving nurses', knowledge, practice, and professional quality of life.
