Actually,the Toastmasters certificate do take time and effort on your part and given the case-study schools that can look like a +ve point(Improved Public Speaking). I am currently on the path of Advanced Communicator and by the time the 2nd round interview invites go out(hope I get one of them!) I would have completed the Advanced Communicator Bronze manual.
Moreover,I actually started a Toastmasters club in my city benefiting the company professionals and the college students in the city. - Maybe a leadership story(Reason I wanted to cite Toastmaster as a certification)
Also,by my profile you can see that I am a reapplicant to some schools that I got dinged from last year so in the reapplicant essay(How you have improved and What else you have done ? ) I can write about improvement in my French language and Public Speaking Skills .(Plus the fact that my paper was selected for a major article in JPT (a major oil & gas journal)).
And the French certificate is equivalent to a MA in French in India so I guess that would carry some weight.
It takes time and effort to explain, so if my comment helped you kudos does rev the engines
