Revisions of tests are becoming a fact of life (Butcher, 2000) Tulsky and Ledbetter (2000) say that a horse put together by a committee need not resemble an elephant but rather may be better, more powerful, and ultimately more satisfyingly a horse Changing from a ‘beloved and relied-upon test’ to an improved updated version is daunting Few people give up an old shoe without a struggle
Psychological tests are susceptible to the effects of time It is important for tests of child development to be updated regularly to ensure that they continue to accurately reflect stages of development in a modern context, and to maintain links with the broader educational context
One challenge when updating a test is the thin line between modernisation and retaining the original spirit of the measure
The team tasked with the revision of the Griffiths Mental Development Scales has tackled this quandary from the foundation up, distilling the true essence of the measure whilst rigorously holding it up to the needs of modern practitioners and up-to-date theory and psychometric influences
Extensive research at the outset of the project recognised the predominance of new attitudes to early learning in 0 to 6 year olds The findings of this research highlighted the need for a more extensive revision than originally anticipated
