<br/>Fluctuation correction to Adam-Gibbs model of cooperative relaxation properties in glass-forming liquids is determined. We show that the characteristics of the correlation volume or the number of structural units are governed by the distribution of relaxation times, the Narayanaswamy-Moynihan nonlinearity parameter, the steepness index of the glass forming liquid, and changes in the heat capacity at the glass transition temperature. We predict the configurational fraction, the fraction of excess entropy that represents the configuration contribution, at the glass transition temperature for several glass forming liquids.<br/>
