The article presents modern trends in testing and assessing learning outcomes in the direction of developing the quality and capacity of high school students. The basic signs of difference between assessing learners' ability and assessing learners' knowledge and skills are also studied and synthesized. A tool to test and evaluate the topic of frictional force in the direction of developing the quality and capacity of students in teaching Physics has been designed. Based on the experimental results of pedagogy at Tuong Duong 1 High School, the effectiveness of the proposed tools has been evaluated, thereby proposing solutions to improve the efficiency of testing and assessment in the direction of developing the quality and competence of students.
