The purpose of this paper is to draw attention to problems that may arise with regard to the validity and acceptance of the CWI because of the use of the equal-weighting procedure. The paper describes several methods that might be used to corroborate or cast doubt on the notion that equal weighting is the optimum combinatorial strategy. The methods described could be used to produce an ordering of the child indicators in terms of their relative importance, as well as to foster important advances in the field of child indicators research.
