Problem: A teacher is concerned because the ratio in her preschool room is 1:12, even though the school's brochure says this center maintains a 1:10 ratio for 3- and 4-year-olds. A 1:12 ratio is permitted by licensing. The teacher decides to talk with her director about the ratio in her room and urge her to either abide by the ration described in the brochure or modify that description of the program. Which principle of the NAEYC Code of Ethical Conduct best relates to this situation? Select only one. Need Professional Help?
