This Army promotion points calculator is based on DA Form 3355; the Army Promotion Point Worksheet (PPW). If you would like to print out a copy of the actual DA Form 3355, there is one available here.
To use the Army Promotion Points Calculator, you need to first select the rank that you are trying to make points for. This is because each section is worth a different amount of points based on your selection. You can then expand each section and fill in your information. It is self-explanatory. But, make sure you look at each section and the small print to ensure you are putting courses in the right sections. This is often a cause of issues in the Military Education section.
