(a) An injured employee who, as a result of injury, is or may be expected to be totally or partially incapacitated for a remunerative occupation and who, under the direction of the Director is being rendered fit to engage in a remunerative occupation, shall be paid additional compensation necessary for this maintenance, not exceeding $25 a week. The expense shall be paid out of the special fund established in section 44 of the Act, 33 U.S.C. 944. The maximum maintenance allowance shall not be provided on an automatic basis, but shall be based on the recommendation of a State agency that a claimant is unable to meet additional costs by reason of being in training.

(b) When required by reason of personal illness or hardship, limited periods of absence from training may be allowed without terminating the maintenance allowance. A maintenance allowance shall be terminated when it is shown to the satisfaction of the Director that a trainee is not complying reasonably with the terms of the training plan or is absenting himself without good cause from training so as to materially interfere with the accomplishment of the training objective.
