I have a Masters degree endorsed in Special Education and worked fr 2 years as RTLB Cluster Manager in Mangere & Otahuhu so have a special interest in students with special needs and especially those in the mainstream.
In 2014 I worked with the Ministry of Education in Lower Hutt supporting 50 schools (Principals & SENCOs) in ensuring that their schools were inclusive places for all students .
There are useful guides here that should help if you have a student with special needs in your classroom.
Every school will have an RTLB Service Cluster in which RTLBs are trained in special education and can help teachers with a child/children needing extra support
