The study of masonry is one of the world's oldest and most respected crafts. Masonry construction existed for thousands of years. The remains of stone buildings date back 15,000 years, and the earliest manufactured bricks unearthed by archaeologists are more than 10,000 years old. These bricks were made of hand-shaped, dried mud. Among the most well known works of masons are the pyramids of ancient Egypt and Notre Dame Cathedral in Paris.
NCCER's three-level curriculum encompasses modules such as Mortar, Metalwork in Masonry, and Estimating.
