The origin and evolution of circumstellar disks is one of the main scientific quests intimately related with planetary formation, since disks are known to be planetary nurseries. A study of statistically significant young stellar populations, in different evolutionary stages and astrophysical environments, can provide fundamental tests for theories of disk and planet formation. We are presently conducting a systematic broadband infrared wavelength study of ten young clusters of different ages, in order to compare their circumstellar disk frequency. We report our results of JHK photometry of three nearby clusters of our sample, RCW 38, NGC 2316 and NGC 2547.
