accreditation
We offer standard or customised training courses for ESL developers.
The courses can be carried out online using Teams or in your premises or our purpose built classroom.

We have recently introduced a Developer Accreditation service. This accreditation process will allow the assessment of an individual's development skills and their knowledge of the ESL products. As the skills will be assessed by ESL Syndetic, it will be done on a common basis across all ESL Customers. The accreditation can be carried out on your premises or in our purpose built classroom.

Please contact for details.
