Authors should get in the habit of explicitly associating form controls and informative labels (see the example for Checkpoint 12.4). In the meantime, Examples 1 and 2 on this page show the layout of controls that would be relatively accessible to users of screen-readers. It should not be difficult to identify which label is associated with which control.
For all form controls with labels, ensure that:
Example 1: the label is immediately following its control on the same line (allowing more than one control/label per line).
