Scientifically-Based Research Definition

The definition for scientifically-based research is found in the No Child Left Behind Act (20 USC, Section 9101[37]).

As defined by the No Child Left Behind Act (20 USC, Section 9101(37)) scientifically-based research:

  1. Means research that involves the application of rigorous, systematic, and objective procedures to obtain reliable and valid knowledge relevant to education activities and programs; and
  2. Includes research that:
    1. Employs systematic, empirical methods that draw on observation or experiment;
    2. Involves rigorous data analyses that are adequate to test the stated hypotheses and justify the general conclusions drawn;
    3. Relies on measurement or observational method that provide reliable and valid data across evaluators and observers, and across studies by the same or different investigators;
    4. Is evaluated using experimental or quasi-experimental designs in which individuals, entities, programs, or activities are assigned to different conditions and with appropriate controls to evaluate the effects of the condition of interest, with a preference for random-assignment experiments, or other designs to the extent that those designs contain within-condition or across-condition controls;
    5. Ensures that experimental studies are presented in sufficient detail and clarity to allow for replication or, at a minimum, offer the opportunity to build systematically on their findings; and
    6. Has been accepted by a peer-reviewed journal or approved by a panel of independent experts through a comparably rigorous, objective, and scientific review.
