CASLAR（汉语作为第二语言研究）研究运动由纽约州立大学奥尔巴尼分校Istvan Kecskes教授于2010年发起，旨在建立一个“汉语作为第二语言研究”（CASLAR）的新学术领域。CASLAR每两年召开一次国际研讨会，有自己的同名期刊（CASLAR）。

CASLAR的目标是把基于实践和经验的汉语研究引向一个基于科研和理论的新方向。CASLAR力图凝聚全球研究汉语作为第二语言的习得、发展与运用的专家、学者，探讨交流汉语研究领域中知识概念、构想和科研项目。第一届CASLAR国际研讨会于2010年在中国的浙江大学召开。第二届于2012年在台湾师范大学召开。2014年在意大利的帕玛大学（University of Parma）召开了第三届CASLAR国际研讨会。

在此次会议上，CASLAR研究协会正式成立，同时也创建了CASLAR双语网站（http://www.caslarcenter.com/）。

In 2010 the CASLAR project was launched by Professor Istvan Kecskes (State University of New York, Albany, USA) with the goal to establish an independent research organization with its biannual conference, journal and international association and to transform a field from a primarily experience-and practice based discipline into a field based on and supported by research and theory. CASLAR attempts to bring together scholars from all over the world whose research focuses on the acquisition, development and use of Chinese as a second language, to survey available knowledge in the field, exchange ideas and initiate research projects. The first CASLAR conference was held at Zhejiang University, China 2010, the second one was at National Taiwan Normal University, Taipei in 2012, and the third one was at the University of Parma, Italy in 2014. At the conference in Parma CASLAR was transformed into CASLAR Association by the participants.
