This can really be read for any grade level but for this particular activity, I would say 4th-6th. Since using it for older grades it would be a fun way to read a picture book again since they have already transitioned to chapter books, also because most students will be able to catch the metaphors. You could read this book to your class, maybe after having had a career week, maybe even red ribbon week since that is about saying no to drugs. That has a lot to do with making a better person out of yourself. After reading the book to the students they could write a short paper about what they want to be when they grow up and why they want to do that particular job. This is a great gift for graduation!
