Every student could be studying optimally when movements within the zone of proximal development (ZPD). The ZPD among students in a class may diverge. This research tried to analysis of students ZPD in numerical skills on math learning. The study covered 28 third-grade students in elementary school at Padangkeling, Singaraja, Bali. Numerical data understanding of students obtained through the 10 items essays numerical understanding test for elementary school students. Rasch Model analysis is used to examine the properties and quality of numerical understanding tests and to describe each student's ZPD in numeric understanding. This study basically shows that through Rasch analysis it is known that ZPD of students in one class are absolutely different and diverse. There are 11 students identified as having ZPD under the control of the material based on the numerical understanding test so that it requires a special learning program. Four students have ZPD zones that are under some materials requiring more intelligent adult tutors or peers. The other fourth students have ZPD that suited to the comprehensive work in the test, and nine students are students with specific skills who require to look at enrichment in learning program. © Published under licence by IOP Publishing Ltd.
