It should be necessary to achieve a standard that the training school has set and agreed with their accrediting body. If a student is struggling to meet that standard, a good trainer works with them to devise a realistic development plan that may involve continued practice and an assessment at a later date.
A reputable training school will not certify someone who has not reached the required standard and is not ready for it. It puts them, others and the industry at risk.
In some cases, no matter how determined the student and how great the teacher, there are times when a student needs to hear that this is not the career for them as they’ve yet to demonstrate that they can perform the treatment safely. A good trainer would not shy away from having an honest conversation. After all, that training school would be certifying that they’ve trained the student to a competent level to apply lashes! Would you want that person anywhere near yours? I thought not.
Students are usually assessed by observation and questioning to check their knowledge and understanding during their time in class. Further assessment is often done as many good training schools invite students to submit a portfolio of case studies for assessment in order to pass their course. In addition, I specifically ask students to continually reflect and consider what went well and why, what didn’t go so well and why and what will they would do differently next time. If you practice this self-reflection, you’ll continuously improve your service. Otherwise, if you do what you have always done, you’ll get what you’ve always got…that’s not self-improvement.
