There is no specific “highest level” of carpenter, as carpenters can specialize in different areas and may have different levels of experience and expertise. Some carpenters may be highly skilled in framing, while others may be experts in finish carpentry. Some carpenters may also choose to specialize in a specific type of material, such as wood or concrete. In general, the more experience and training a carpenter has, the more highly skilled they are likely to be. Some carpenters may also choose to become contractors, which involves managing and supervising construction projects.
