NDP3 Training courses

Yes. We currently run courses for qualified SLTs. You can find details of the planned courses on our Training page.

When the Covid-19 pandemic has abated, we will run face-to-face courses. Until then, all training is online – please refer to our training page.

We offer standard and bespoke courses for SLTs. Click here for more information.

We don’t run training courses for parents. Each child’s needs are different and methods that may work with one child could be unhelpful for another. A therapy programme should be designed for an individual child by the therapist working with him or her.

Resources such as NDP3 Speech Builder, used under the guidance of a qualified Speech and Language Therapist, can be a useful addition to therapy. Parents should always be guided by the therapist as to how best to support their child.

Some of the organisations listed on our Links page provide advice and support for families.
