each standing committee of the Senate 1 and the House of Representatives shall review and study, on a continuing basis, the application, administration, and execution of those laws, or parts of laws, the subject matter of which is within the jurisdiction of that committee. Such committees may carry out the required analysis, appraisal, and evaluation themselves, or by contract, or may require a Government agency to do so and furnish a report thereon to the Congress. Such committees may rely on such techniques as pilot testing, analysis of costs in comparison with benefits, or provision for evaluation after a defined period of time.
