Standard Navy Methods for Determining BCA Compliance

BCA Requirements
Per DODI 1308.3, there are only two approved methods to determine a member’s BCA:
1) maximum weight for height and 2) circumference measurements. No substitute
methods (e.g., underwater weighing, skin fold calipers, body mass index, bioimpendence,
etc.) of assessment are permitted. All BCA measurements are to be
conducted in the blue and gold Navy Physical Training Uniform (PTU).
The official BCA is final and will not be reversed by a subsequent BCA waiver.
Members must address any potential medical issues prior to the official BCA.
Standards are determined by established maximum weight for height standards.
Per OPNAVINST 6110.1J only certified Command Fitness Leaders (CFL) or trained
Assistant CFLs (ACFL) are authorized to conduct official BCA measurements. BCA
measurements conducted by Medical and/or Morale Welfare and Recreation personnel
cannot be used for official reporting nor do they override measurements taken by the
CFL or ACFL.
