This chapter aimed to discuss the feasibility of embedding computerised adaptive testing (CAT) into Indonesia’s teaching and learning and its implications. As a new testing system, CAT has demonstrated its advantages in assessing learning outcomes compared to paper-based tests. The system not only lessens administrative issues but also reduces measurement errors in estimating students’ levels of achievement. Also, the system provides direct feedback to test-takers that can be used for remedial instruction. Indonesia, as the fourth most populous country and seventh widest geographical area in the world, has been facing a number of problems in administering national examinations. Since computer education is still not very popular among students and teachers, various steps should be taken to improve this situation. Such measures include integrating computer education into the national curriculum, upgrading teachers’ competencies, intensifying computer use, providing more extracurricular programs on computer use and hiring additional computer teachers and technicians. The implication is that students’ readiness for CAT would be enhanced. Its future application would minimise Indonesia’s national examination problems as well as reduce measurement errors and improve the predictability of test results. In addition, teachers can use the feedback from test results to modify students’ weaknesses. In this way, teaching and learning would be more on track as ultimate positive implications of adaptive testing.
