Henceforth be used by teachers in measuring reading, writing, and counting. Reading, writing, and counting are the basic ingredients for elementary school students to be mastered to be able to commence the learning process up to a higher grade. In order to increase the interest in reading, writing and counting, it is required to build a standardized instrument to measure the ability to read, write and count.

Instruments that have been tested validated using Corrected Item Total CorrelationAnalisys and calculation of reliability. Reliability of the measuring instrument reading, writing and counting have an index α ≥ 0.50, so that each instrument is reliable.
