Most contemporary analysts regard illiteracy as a development issue because of the link between poverty and illiteracy. Funding is inadequate and inconsistent and is needed for priority areas such as educator training, monitoring, and evaluation. There is a clear need for investment in capacity development, having a full, sufficiently paid and well qualified professionalized staff, and increasing the demands for adult education professionals. The majority of adult educators are untrained, especially in basic literacy. Governments often employ school teachers and others in adult education posts rather than experienced adult educators. Many of the difficulties experienced could be solved by an allocation of resources to meet the needs (adequate funds, more staff, appropriate training for staff and suitable material). Underfunding is a huge threat to the sustainability of these programs, and in some cases, to their continued existence. The best-reported data on funding is about adult literacy and non-formal education programs. Funding for continuing education, either academic or vocational is provided and reported on, but little data is given on its financing. Funding may come from public or private sector sources. International and foreign aid is also likely to be important. The costs of much adult education seem to be kept artificially low by the use of state facilities and by the extremely low salaries paid to many adult education specialists.
