I organise the work experience placements at my work and rocky is absolutely right about the purpose - it's to experience the responsibilities of getting to work on time, interacting with others,behaviours in the workplace etc. You will find that most places will not take advantage of your daughter's intellect, H&S, data protection blah blah often don't allow them to, the work places chosen will also have been through a rigorous assessment before being allowed to accept young persons so not too many worries there. Ask her what she's interested in, maybe she'd prefer an office type placement or help at a school or maybe something off the wall that has no connection with her future.
