Discovered or "found" space in a school system most often appears as (1) space that a school system already owns in its outdated buildings and which is being used inefficiently; and (2) space lying close at hand in warehouses, factories, industrial plants, or in little-used public buildings. Found space is one solution to the problem of providing needed school space despite an inability to raise money to build new schools. Many school systems are exploring economical alternative solutions to the school space problem that would provide new or modernized old space at a reduced cost, more space or better space for the same amount of money, greater use out of existing space, and less expensive alternatives to conventional school space. This document collects all the alternatives known to EFL that appear to be actually working or that have been planned to help solve school problems. (Author)
