Elklan was established in 1999 by experienced speech and language therapists Liz Elks and Henrietta McLachlan. The pair recognised a need for more efficient staff training in order for teachers to be more effective in their support of children with speech, language and communication needs (SLCN). 

Since 2001 Elklan has trained over 1,400 speech and language therapists as tutors and 714 specialist teachers as co-tutors.

Most of the trainers work in the UK, but in recent years the organisation has gained an increasing number of tutors in Ireland, Australia, Luxembourg and The Falkland Islands.

The hugely successful Train the Trainer programme has enabled training to be cascaded to over 30,000 staff working in pre-school, primary and secondary education in both mainstream and specialist settings as well as parents.
