Directs the Secretary of Labor to enter into a contract with a non-governmental entity to conduct a longitudinal study of a statistically valid sample of each of the following groups of individuals over a period of at least five years: (1) veterans who have received intensive job counseling, training, and placement services; (2) veterans who did not receive intensive services but who otherwise received services; and (3) veterans who did not seek or receive services.

Requires the study to include the collection of specified information for each individual who participates in the study, including:

• the average number of months served on active duty,
• the distribution of disability ratings,
• unemployment benefits received,
• the average number of months employed and average individual and household annual income,
• employment status,
• whether the individual believes that any service received helped the individual to become employed,
• use of educational assistance,
• participation in a vocational rehabilitation program,
• conditions of discharge or release from the Armed Forces, and
• demographic information.

Directs the Secretary to submit annual reports on the outcomes of the study that include any information the Secretary determines is necessary to determine long-term outcomes of the individuals in such groups.
