Notes on Usage

The term originated in surveying (literally a "mark on a bench" or other permanent object). While "bench mark" (two words) is the traditional form and is still used in technical surveying contexts, "benchmark" (one word) has become the dominant and preferred spelling for its figurative meaning as a standard for comparison in business, technology, and general usage.
