Introduction The 1st Griffiths course in Portugal, directed by Psychologist Dr. Michael Huntley, was held in 1988; The first portuguese tutors were recognized in 1991 by ARICD; The first portuguese edition of the 0-2 Scale (Revision 1996) was published in 2007 and the 2-8 Scale (Revision 2006) in 2008. The translation and adaptation of the application norms was made by the Portuguese Tutors in collaboration with CEGOC, responsible for editing; The Griffiths Scales are frequently used in Portugal to assess the child development;
Aim of the Study In the conclusions of the study “Griffiths profiles in a group of premature children with PVL – a comparative study” (2010), was raised the need to validate the british norms in a portuguese sample. The passed year, the Portuguese Tutors and a research team from ISPA-Instituto Universitário started a project whose aim was to validate the GMDS-ER to the portuguese population. This study presents the results of a portuguese sample that will allow, comparing the scores of british stantardization, to validate the appropriateness of the original tables in the clinical assessment of portuguese children.
Methodology Procedure: All children were assessed with the Griffiths Scales at their schools; A report of the results was sent to the parents and, if allowed, to the schools; The statistical results were based on the raw scores;

Conclusions As observed in previous researches done in Portugal with other scales that assess cognitive areas (WISC III e WPPSI III), in the present study we also had lower results when comparing the portuguese and the british total samples. Looking at the subscales in the different age groups: o Good results in the subscales B and C can reflect the cultural and pedagogical aspects most valued in portuguese pre-school: autonomy and communicative interaction; o The lower results shown in the subscales D (specially in the graphomotor skills) and F (specially in the conceptual formation) may be explained by the fact that kindergarten acquisitons, such as concepts, phonetics, graphics, etc. only begin to be worked out at the age of 5.
Study Limitations and Future Research The sample was chosen for convenience, was restricted to an urban area (Lisbon) and mostly to a medium/high sociocultural level. The results points out the importance of continuing in this path, using a larger and more representative sample of the population at national level This pilot study makes us think about the importance of standardizing the GMDS in the portuguese population.
