As Adult basic Education programs become more popular more and more employers are offering their employees the opportunity to take part in the programs. However even with the best will in the world employers must take into account the imperatives facing their business. They have to ensure that targets are met and that the business remains viable. Goodwill alone will not keep the business afloat. For this reason most providers of ABET services will hold classes on site to minimise the disruption to everyday activities. Workers can then attend classes totaling between four to six hours a week which will allow them to complete an ABET level in between four to eight months.
