All components were approved with a factor load above 0.6 and Butler coefficient with 0.9 indicated a high correlation between experts. Conclusion: Professional ethics is one of the basic and serious needs in various sectors of education in the country and can provide the grounds for overcoming this situation of recession and lack of trust and confidence and cultural confusion.
