Under the background of all-round implementation of “Double Reduction” policy，special education teaching and research plays a key supporting role in the improvement of special education teaching quality in Beijing. Benefiting from policy guarantees and municipal-level overall planning，Beijing City’s construction of special education teaching and research system has been pushing forward，team building has been strengthened；the mechanism operation has been continuously improved，a “municipal-district-school district-school” four-level special education teaching and research system has been initially formed；multi-theme multi-mode teaching and research methods are operating in an orderly manner；the promotion mechanism of integrated research and training，integrated research and publicity，research-facilitated improvement has shown initial effects. In addition to the demand for pushing forward high-quality development of special education in a new stage，Beijing City’s special education teaching and research also faces challenges such as low proportion of full-time teaching and research staff，to-be-strengthened linkage between teaching and research at all levels，to-be-deepened teaching and research themes，and to-be-refined-and-disseminated achievements，which are also new focus and growth points for the improvement and development of special education teaching and research in Beijing during the “14^th Five-Year Plan” period.
