The BYOD (Bring Your Own Device) concept provides extended opportunities for implementation of ICT into all forms of learning. The aim of this work is to propose optimum variant of arrangement of mobile testing of learning results of students using BYOD. The article reviews the scientific literature on the problem under study and presents the advantages of BYOD technology in testing learning outcomes. On the basis of online survey of the teachers, IT experts, and network administrators, the opportunities of mobile applications have been compared during testing of learning results, the optimum variant of mobile testing of learning results of students using Google services has been proposed. The results of the study show that the use of the BYOD concept expands the boundaries of testing, makes the testing procedure more flexible and systematic, introduces gameplay elements into the testing procedure, and contributes to the actualization of students' knowledge. The use of cloud services of the Google search engine for testing within the BYOD concept has several advantages over similar software services: comprehensive support of the testing system from creating appropriate forms to saving the results in the cloud data storage for processing test results and managing the testing system based on using the Google Calendar service, the ability to create a budget testing system due to the use of free Google services.
