The format is {{s-npo|parameter}}, where parameter is replaced by one of the parameter names shown in the following table. The first column displays the header and the second column contains the parameter name.

From the Roy Williams article:

{{s-start}}
{{s-npo|bsa}}
{{s-bef|before=[[Jere Ratcliffe]]}}
{{s-ttl|title=[[Chief Scout Executive]]|years=2000 – 2007}}
{{s-aft|after=[[Robert J. Mazzuca]]}}
{{s-end}}

• For new titles, replace {{s-bef}} with {{s-new}}.
• For incumbents, replace {{s-aft}} with {{s-inc}}.
• For incumbents with a designated heir, use {{s-inc|heir=designated heir}}
• Use only the year that the incumbent took office followed by "– present"
