Students at all times must wear an approved shirt with the Amarillo College logo during class meetings.  Failure to wear approved shirt will result in an absence for the entire meeting. Tools and equipment specified for this class and any preliminary class in the curriculum are to be furnished by the student. Failure to dress for work or bring needed equipment will count as an absence. All tools should be properly used and cared for, thus allowing for longevity and safety of both the user and the tool.
