I am a new learner for judge the flowering size and award score.

Did anyone telling me that where have the information to know the judgment ?

How to let my paphiopedilum to take the awards score ?

The measuring sequence for AOS judging is explained in the judging Handbook.
Basically the sequence for paphs is natural spread, vertical spread; dorsal sepal- width, length; ventral sepal- width, length; petals -width, length; pouch- width, length. The sequence basically follows the flower parts from the perimeter to the base of the flower.

The natural spread is measured without flattening the segments, it is as the flower is expressed naturally. All other parts can be moved to measure and are measured at the widest and longest points. All measurements in centimeters.
