A bricklayer, which is related to but different from a mason, is a craftsman and tradesman who lays bricks to construct brickwork. The terms also refer to personnel who use blocks to construct blockwork walls and other forms of masonry. In British and Australian English, a bricklayer is colloquially known as a "brickie". A stone mason is one who lays any combination of stones, cinder blocks, and bricks in construction of building walls and other works. The main difference between a bricklayer and a true mason is skill level: bricklaying is a part of masonry and considered to be a "lower" form of masonry, whereas stonemasonry is a specialist occupation involved in the cutting and shaping of stones and stonework.
Bricklayers occasionally enter competitions where both speed and accuracy are judged. The largest is the "Spec-Mix Bricklayer 500" held annually in Las Vegas, Nevada, USA.
Bricklaying and masonry are ancient professions that even centuries later require modern training. Bricklayers usually go through a formal apprenticeship which includes about three to four years of on-the-job training combined with classroom instruction. Unions and many employers offer these apprenticeships. To become an apprentice, one must be at least 18 years old and have graduated high school. Masons must attend trade school and/or serve apprenticeships requiring they demonstrate they know how to protect homes from humidity or water ingress, know about thermal insulation, and know about the science of construction material and occupational health and safety. While some online sites say they can get you certified in a little as 30 days, most bricklayers today attend trade or technical schools and receive in-depth and thorough training.
