Abstract
The aims of this research are: (1) to measure the difficulty level of grain test of mathematics achievement of third grade student at elementary school, (2) to know the differences of mathematics achievement test for third grade student of elementary school, (3) instrument reliability test of mathematics learning achievement of third grade students of elementary school. The research method used is research development, the data analysis to know the information about grains of mathematics test instrument using ITEMAN program. The results show: (1) the test which developed has difficulty level in the range 0,30 ≤ p ≤ 0,70 with accepted category, (2), the test which developed has differences level in range 0,30 ≤ B ≤ 0,39 and 0,40 ≤ B ≤ 1,00 with accepted category and satisfy, and (3) the test which developed has reliability coefficient of 0,783, show that mathematics test instrument give measuring result that stabile and consistent.
