To help new employees grasp complex lab procedures quickly, start by providing clear, step-by-step written instructions and visual aids, such as diagrams or videos, to simplify the procedures. Pair them with experienced mentors for hands-on training and practical demonstrations. Encourage them to ask questions and provide regular feedback to address any confusion promptly. Implement a structured onboarding process with frequent check-ins to assess their understanding and adjust training as needed, ensuring they build confidence and proficiency efficiently.

Continue to have weekly huddles or 1:1 with new employees to keep track of progress regarding new procedures. Engage with new team members and be receptive to new ideas or new processes.

One technique that I find works well, is have clear directions, show the employees how the process should be performed/completed, then have them try with you present. This allows them to ask any questions and for you to provide them with clearer or further direction. It also shows them that you lead by example and don't mind teaching and getting your hands dirty.
