Circular Electron Position Collider (CEPC) is proposed as a Higgs or Z factory. This work introduce the R&D progress of CEPC HCAL. Three detector technologies including RPC detector, GEM detector and plastic scintillator were researched for CEPC HCAL sensitive detector. For RPC detector, we corporation with CALICE collaboration and do some analysis on beam test result. For GEM detector, some module was tested. For plastic scintillator, different size detector cell was tested by Sr-90 source and cosmic ray. In general, some progress of CEPC HCAL has been made.
