This research focused on making applications to determine the dominant multiple intelligences. Everyone has eight different intelligences that reflect different ways of interacting with the world. The dominant multiple intelligence needs to be known so that the child's growth and development is in accordance with his or her talents and interests. Therefore, it is necessary to make an application with tools that have been tested by experts, which can determine the level of intelligence so that the potential of children can be developed. This application was created using the extreme Programming software development method. The reasons for the choice of this method were because the resources to create the application were readily available, the programming was conducted by a small team, and the application development time was short. This application used the PHP and MySQL by displaying a list of 24 questions that had to be filled out by the users. The application testing method used black box testing. The accuracy of the application was 100% from 150 respondents who used this application. The output of this application is a sequence of multiple intelligences owned by users ranging from linguistic, logical-mathematical, musical, spatial, kinaesthetic, intrapersonal, interpersonal abilities, and naturalist.
