Second, as ILO courses are developed in different fields,
it will be important to test them rigorously to see how costeffective
they are in at least sustaining and possibly improving

in large public university systems, which may be willing to
pilot such courses. Hard evidence will be needed to persuade
other institutions, and especially leading institutions, to try
out such approaches.
