General Metals Proficiency Based Clearance

Members who are already proficient in the subject matter may apply to receive a clearance by demonstrating a core set of skills and knowledge that allow them to safely and effectively use the equipment.

Most tools in the shop require clearance before solo use. Each tool is different and most are expensive and/or delicate.

During a Proficiency Based Clearance Instructors will provide Protohaven specific customs and rules for the equipment but will not provide technical instruction on the operation of the hardware, or software.

If a member needs to gain additional knowledge or skill they should take a Basic Skills Class to learn the required skills.

The items that will need to be demonstrated to gain the Proficiency Based Clearance are:
