NDP3 is a complete resource - from pre-speech to connected speech - and includes a range of enhanced and unique materials for assessment and therapy. It starts from pre-speech motor skills, for children who need this level, and works systematically to connected speech.

NDP was originally published in 1985, modified in 1992 and considerably updated, expanded and enhanced in this third edition, NDP3, published in 2004, reprinted in 2005, 2006, 2007, 2009, 2010, 2012.

NDP3 remains the only published resource of its type in the UK and is used by therapists throughout the world.

In summary, NDP3:

	Is suitable for any child with a speech disorder.
	Is a complete resource, spanning pre-speech to connected speech levels.
	Provides for parental/school involvement in therapy.
	Is most suitable for the 3-7 year age range but can be adapted for younger and older children.
	Affords great therapeutic flexibility.
	Provides detailed guidance on planning and management.
	Is 'clinician-friendly.'
	Ensures that therapy remains fresh, engaging and stimulating.

NDP3 can be used with any child with a speech disorder, but the therapy approach is most suitable for children who have significant difficulties in producing single consonant and vowel sounds and whose connected speech is characterised by typical “dyspraxic” features such as sequencing difficulties, inconsistency, speech sound omissions and substitutions and supra-segmental difficulties.

NDP3 is designed to be used under the direction of a speech and language therapist, who has the clinical skills to plan and implement therapy based on an individual child's speech profile. However, parents and school support staff have a crucial role to play in carrying out practice exercises away from the therapy sessions.

Presentation
The therapy approach is presented through pictures. Single consonants and vowels are represented by picture symbols and words of different phonotactic structures, phrases and sentences are depicted by simple attractive line drawings.

Flexibility
The NDP3 Manual provides therapy advice and guidance, but it is not prescriptive. A speech and language therapist has the flexibility to plan an individual therapy programme for a specific child using the materials.

The NDP3 Manual provides very detailed information on treatment planning and management. Speech and language therapists can consult the manual for guidance on where to start and how to progress in small achievable steps and what strategies to adopt to deal with problems.

Clinician-friendly
NDP3 aims to be “clinician friendly” by providing therapy cards to use in therapy sessions and over 500 photocopiable worksheets, to use in both therapy sessions and for homework practice.

Suitable age range
The NDP approach is most suitable for children aged 3-7 years, but it can be adapted for younger or older children.

Continual stimulation
The therapy approach is based on frequent, repetitive practice to learn and establish new skills. The NDP3 Manual provides hundreds of ideas for activities, tasks and games to ensure that therapy remains engaging.
