All staff who are working in centre-based programs and who are included in the child-to-staff ratio must hold some type of Child Care Worker certification.  There are three levels of certification outlined in the Yukon Child Care Act, with an additional two levels of certification described in policy.  Each level also describes the number of hours of study that must be completed in various "streams", which include Health, Child Development, Self-Esteem, Methods, Field Placement and Electives.

• Child Care Worker I: A person who has successfully completed a 60 hour introduction to Early Childhood Development course or equivalent. If two 30-hour courses are used, they must be from different streams;
• Child Care Worker IA (in policy): A person with Child Care Worker I certification who has also completed additional course work in each of the streams described above, but has not yet completed one full year of training;
• Child Care Worker II: A person who has successfully completed one year of training in Early Childhood Development or equivalent;
• Child Care Worker IIA (in policy): A person with Child Care Worker II certification who has also completed additional course work in each of the streams described above, but has not yet completed two full years of training;
• Child Care Worker III: A person who has successfully completed two or more years of training in Early Childhood Development or equivalent.

In centre-based programs, 20 percent of staff must meet or exceed the Child Care Worker III qualifications, an additional 30 percent must meet or exceed the Child Care Worker II qualifications, and the rest must meet or exceed Child Care Worker I qualifications.
