The differences between the GMDS-ER and the new Griffiths III represent an evolution in developmental assessment based on the latest research and theory, and building on the best of the past.
Wechsler (1958) articulated that observing individuals while they solve problems provides an opportunity to gather qualitative, clinical information. This followed in the tradition of the Method Clinique, developed by pioneers such as Jean Piaget and Ruth Griffiths (1954), who observed children at play and in solving problems within their environment. Not only did this ecological systems approach predate Bronfenbrenner (1979), it is reflected in the new protocols where more space has been allocated for observations which may be quantified in terms of samples of behaviour and language. In addition, more advanced protocols will be developed to augment the clinician's observations and analysis.
The new Griffiths III also reflects the cumulative, quantifiable feedback from clinicians in the field, advances in statistical analysis and norming and research into children's development (from the neurodevelopmental to emotional regulation and play). But the Griffiths III also represents a significant development; more than 80 percent of the Griffiths III has been redesigned. It is more streamlined, in terms of ease of administration (fewer disparate items, many of which have been integrated into the 'Quiet Book'), reduced in terms of the number of items (by 36%) and the age range to be evaluated (birth to 5 years 11 months), modernised in terms of the stimulus materials and more integrated in terms of the norms structure and use of protocols. The administrative sequence has been made straightforward. Moreover, the materials can be cleaned. There will not be separate norms for the 0 to 2 year-old cohort and another for the 2+ year cohorts in the Griffiths III so it will constitute a seamless assessment. In addition, the new norms will address the 'Flynn effect' and minimise cultural bias. At the same time the age format structure will be reintroduced from earlier versions. Moreover, the domains of assessment have been reduced from 6 to 5.
The Foundations of Learning Subscale (A) has replaced the Performance and Practical Reasoning Subscales of the GMDS-ER. It will evaluate various aspects of cognition such as different types of attention, processing speed, aspects of executive function such as flexibility, dimensions of reasoning, curiosity and creativity, organising information and planning solutions, concept formation and sequencing thought (Stroud, 2016). It also incorporates various aspects of visual and auditory long-term and short-term memory as well as play (Stroud, 2016), a by-product of cognitive, social and emotional development. Further, it taps visual sequencing in the Picture Arrangement and Series sub-tests.
The Language and Communication Subscale (B) has been refined so that differences between expressive and receptive Language on the one hand and syntactic, semantic and pragmatic language (Paradice, 2016) on the other have been made more explicit and amenable to further consideration. Memory has also been incorporated into the Scale. In conjunction with the Personal, Social Emotional Scale (Subscale D), it will provide useful information in the differential diagnosis of certain neurodevelopmental disorders.
The Eye and Hand Coordination Subscale (C) has been restructured so that it is more contemporary and fun to use by children and in line with the latest research on neuro-physical development (Forssberg, 1998). New tasks include putting rings on a pole (a prelude and form of scaffolding for bead threading), using playdough to make shapes (which also provides information on tactile sensitivities), using Connector Blocks to evaluate strength, imitating finger movements and using their index finger to track 'trails' and employing 'Construction type pieces' to construct 3 dimensional objects and tap bilateral asymmetric coordination (Bloomfield, 2016).
The Personal, Social Emotional Subscale (D) has undergone a major revision. It breaks personal-social-emotional development into a finer grained analysis so that it transcends mere audits of adaptive behaviour. It measures the capacity to 'read' facial expressions', empathy, 'theory of mind' and 'perspective taking', self-concept and capacity for self-evaluation at the 5 year 11 month old level and moral reasoning (Lane, 2016).
The Gross Motor Subscale (E) has been modernised, safety has been accentuated and the new constructs of Postural Development and Motor Sequencing have been incorporated in the new scale (Green, 2016).
Overall, the new Griffiths III represents, conceptually, a significant advance in developmental assessment which can be used with a range of populations and contribute in a practical way to the learning plans of those in need.
In the final analysis, assessment and diagnosis is dependent on the clinician's and researcher's capacity to carry out a comprehensive investigation, where data is collected from many sources (including using assessment tools), various hypotheses explored and the professional's nuanced clinical skills and judgement are used to maximise the intervention outcomes for the child, the family, and other institutions, such as schools. Its strength is that it is a reliable tool that has, and continues to, yield efficacious results with special populations from birth to 5 years 11 months of age and informs interventions in the form of Individual Educational Plans (IEPs).

Note from Hogrefe:
Griffiths III reflects contemporary knowledge of child development. All equipment is child-friendly and designed to keep small children engaged and at ease.
If you are a trained user of the existing Griffiths Scales, you will need to undergo training in the new measure via an e-learning package included in your new kit. If you are a new user of Griffiths, there will be an e-module to complete, plus a shorter in-person training course. Details of Griffiths III training will be announced on our website.
Griffiths III is due late Spring, however we will start taking pre-orders prior to publication. Details will be announced on our website. To receive dedicated Griffiths III updates via email, we invite you to join our Griffiths III mailing list. You'll also find information about our distributors in Australia, South Africa and more.
