      <abstract xml:lang="en">&lt;p&gt;The Bayley III was adapted for dutch children and Dutch norms were created in order to develop the Bayley-III-NL&lt;/p&gt;&lt;p&gt;The Bayley Scales of Infant and Toddler Development-third edition (Bayley-III) are frequently used to assess early child development worldwide. However, the original standardization only included US children, and it is still unclear whether or not these norms are adequate for use in other populations. Recently, norms for the Dutch version of the Bayley-III (The Bayley-III-NL) were made. Scores based on Dutch and US norms were compared to study the need for population-specific norms.&lt;/p&gt;&lt;p&gt;Scaled scores based on Dutch and US norms were compared for 1912 children between 14 days and 42 months 14 days. Next, the proportions of children scoring &lt; 1-SD and &lt; -2 SD based on the two norms were compared, to identify over- or under-referral for developmental delay resulting from non-population-based norms.&lt;/p&gt;</abstract>
