Worth is an outcome of an evaluation and refers to the value of the evaluand in a particular context, as opposed to the evaluand's intrinsic value, which is its merit. Worth and merit are not dependent on each other, and an evaluand (e.g., a doctor) may have merit (she is a highly skilled cardiologist) but have little worth (the hospital needs an anesthesiologist). The opposite is also the case (the hospital has found an anesthesiologist but not a very good one). The worth of an evaluand requires a thorough understanding of the particular context as well as the qualities and attributes of the evaluand.
