Bambino categorizes Sitters based on three experience levels:  Junior, Standard and Advanced. Junior Sitters are at least 13 years old and they have some babysitting experience. Standard Sitters are generally at least 16 years old, however experienced 15 year olds can be upgraded to Standard Sitters based on a variety of measures. Advanced Sitters are generally at least 19 years old, however very experienced 17 and 18 year olds can be upgraded to Advanced status based on a variety of measures. Some of the variables include the number of recommendations a sitter has, their hours in the Bambino platform, and their overall rating.
