MIT Scheme is an implementation of Lisp. The "MIT Scheme Reference Manual" explains its the relationship to a Scheme standard in this way:
Throughout this manual, we will make frequent references to "standard Scheme", which is the language defined by the document `Revised^4 Report on the Algorithmic Language Scheme', by William Clinger, Jonathan Rees, et al., or by the IEEE Scheme standard (in fact, several parts of this document are copied from the `Revised Report'). MIT Scheme is an extension of standard Scheme.
