Abstract. Mathematisation is very important process in solving contextual mathematical problem or real world problem. Therefore, the objective of this paper is to describe the mathematisation of female preservice teacher student with high mathematics ability in solving mathematical literacy problem with personal context. This study uses descriptive research with qualitative approach. Data is collected by giving the mathematical literacy problem and interviews. Mathematisation is described by using  mathematisation steps. The mathematisation of female preservice teacher student with high mathematics ability in solving mathematical literacy problem with personal context as follows 1) formulate real world problem (contextual problem) into the mathematical problem is conducted by making big cube from a number small cubes, 2) use concepts, facts, procedures and mathematical reasoning to get mathematical solution from mathematical problem is reached by determining the number of small cubes in each side, 3) interpret mathematical solution to the real world problem is done by make conclusion from solution, and 4) the last step, evaluate the solution with the context of problem is known by reading again the real world problem and check the solution. Preservice teacher student’s mathematisation is an important process in solving mathematical literacy problem.
