The development of motor competence in early childhood substantially contributes to successful engagement in sports and other physical activities. In view of the decreasing levels of physical activity and motor skills in children over the past decades, an appropriate assessment and monitoring of motor competence in early childhood is invaluable, for both research and practice [1Fransen, et al. Convergent and discriminant validity between the KTK and BOT-2 short form testing batteries for motor competence Res Develop Disab 2014 ;  35 : 1375-1383 [cross-ref]

Five hundred and thirty 5- and 6-year-old children (277 ♂ and 253 ♀; mean age=5.95; SD=0.57) were tested by practiced assessors on the KTK and MOT 4-6 during the same day. From the raw scores, a Motor Quotient was calculated based on normative data of the KTK and MOT 4-6.

A Pearson correlation demonstrated a moderately strong positive association between KTK Motor Quotient and MOT 4-6 Motor Quotient (r=0.605). Crosstabs showed a fair level of agreement between the two tests (K=0.313; P<0.001).

These findings provide some but limited evidence of convergent validity between KTK and MOT 4-6. The explanation for the lack of stronger associations probably lies in the different concepts that are evaluated in each test battery. The implication of this moderate level of agreement between KTK and MOT 4-6, is that practitioners and/or clinicians should be aware of possible categorisation errors when using the KTK or MOT 4-6 test to detect motor impairments.
