L2 Syntactical Complexity Analyzer (L2SCA) developed by Xiaofei Lu at the Pennsylvania State University, is a computational tool which produces syntactic complexity indices of written English language texts.[1]

The L2SCA has been used in numerous studies in the field of second language writing development to compute indices of syntactic complexity. [2][3]
