The aim of this study was to extract psychometric properties of the mathematical fluency and calculation tests for students of the primary stage (level) in the Jordanian environment. To achieve this goal, the test instructions were translated, and the mathematical writing was modified to suit the target sample. The test consists of two basic tests, including the calculation of the calculation (50) item, and the test of mathematical fluency (100) items. The study sample consisted of 3160 students - ordinary students - from grades 2 to 5, who were selected according to the random sampling method of Jordanian schools. The results of the study showed that all the values of the consistency coefficients / item statistics for the MFACTs for all grades in the standardization sample, and for the overall test score were greater than or equal to 0.699. On the other hand, mathematical fluency test was greater than or equal to 0.890. The values of the reliability coefficients ranged within the internal consistency / item statistics using the Cronbach Alpha formula to test the calculation between 0.699 for the second grade, and 0.876 for the fifth grade. Similarly, the reliability coefficients ranged from 0.890 for the second grade and 0.901 for the fifth grade. The coefficient of repeatability (Test- Retest) of the test for the total sample was 0.87 in the calculation test and 0.90 in the mathematical fluency test. The results further implied that there were no statistically significant differences between the two groups in the performance of the test according to the gender. As for the performance of the test, the average performance of the study sample steadily increased in the different grades. The correlation between the MFACTs and the mathematics student average in the previous year was 0.905 for the test and 0.486 for the mathematical fluency test
