The field of language policy and planning is clearly a sub-field within applied linguistics. It generally does not draw heavily on formal linguistics, except for aspects of corpus and status planning. However, it does draw extensively from a range of disciplines in order to plan, implement, and evaluate language policies that respond to the needs of stake holders of various types. Despite continuous development of the field, aspects of language policy and planning need to be developed further. One of the key areas where policy can be enhanced considerably is in the area of policy and planning evaluation. This direction of inquiry is also relevant to a number of other areas within applied linguistics.
