Hi, if this relates to adults then setting's will have expectations for staff behaviour, they'll want colleagues to be polite, courteous and respectful, supportive, informative and welcoming. You'll be required to work within the guidelines that are set out so that everyone can work together & toward the same goals.
Monitoring & summarising your own practice can be done through annual appraisals, meetings with peers and more senior leadership, any complaints, disiplinary and grievance policy. Times where you're able to reflect and evaluate your own performance eg. after a day's session, before a session, when you know there are or were challenges involved.
Monitoring own conduct and behaviour requires benchmarks/standards and the knowledge of what's expected of you so that you can see what differences might exist between the two eg.
Your language - spoken, body and professionalism
Jewellery, clothing and accessories
Attitude
Punctuality
Ask your placement/workplace if they have a staff handbook that explains conduct and the systems they have in place for helping employees examine their own professional practice. Your job contract, roles and responsibilities might also help.
