The below info is from the state website in NY. I am under the impression that things could be very different state-to-state. All my work experience has been in the co-teaching model.
Consultant Teacher services are defined as direct and/or indirect services provided to a school-age student with a disability in the student's general education classes, including career and technical education classes, and/or to such student’s general education teachers.
Direct CT ( Consultant Teacher) services mean specially designed instruction provided to an individual student with a disability or to a group of students with disabilities by a certified special education teacher to aid the student(s) to benefit from the general education class instruction. Direct CT can be combined with indirect CT services.
Indirect CT services mean consultation provided by a certified special education teacher to a general education teacher to assist the general education teacher in adjusting the learning environment and/or modifying his/her instructional methods to meet the individual needs of a student with a disability who attends the general education class. Indirect CT can be combined with direct CT services.
