Well personally, I would feel that I don't need the trophy and having some silverware at the school might encourage other people there to aspire. Apart from motivating the pupils, the school itself might feel differently about sponsoring them if it wasnt going to get to showcase the winnings. Others could lose out by seeking a few bits of metal for your own mantlepiece. I have a few odds and ends over the years but to be honest I would have been just as glad to know they were somewhere people saw them - they just gather dust and take up space.
Can I claim my trophy's?

how did you totally delete your last comment? I dont think that you could force them to, but it wouldn't hurt to ask.

I don't know about what the etiquette in your country, but where I live, it is generally accepted that the school you represented is entitled to the tropies you've won.
Nonetheless, if you're careful not to be rude, you could probably make a polite request for the trophy (though it would definitely be risque).

At your age I can understand your feelings. But later in life you will come to see the other side, and if your name is on the trophy and winning for your school, it is resting at the best place possible, trust me on that one. I won alot of trophys some in chess and other areas even in management skills, and they all gathered dust like some one already said and my wife trash canned them Try not to belittle yourself by asking for it, you are too smart and will have alot more important things you will achieve in the future!! Thats why I am you uncle and proud of you!!!!

What is the reason that you want the trophies? If it is for other people to see? Then as other's said, they are in the best place already.
If it is so that you can see it and gain some nostalgia from it, you might be better off making a nice framed photo/collage of your chess accomplishments and photos of games played. This is a much nicer piece for your home than trophies. When I left my last job, they were going to give me a small statue with a plaque, but someone had the great idea to make a photo thing (I don't know how to describe it, has photos of my time there and my collegues with a small plaque) which looks great on my wall and gives me much better memories. Plus it hangs on the wall which is great.
There is always the idea to become a chess coach at this school too. Maybe you could "give back" to the younger generations and be the supportive coach that you felt you missed out on. Believe me, the feeling you will get from supporting younger players far outweighs any that you may receive from a cup on your shelf.
Just a few thoughts, and congratulations on your accomplishments

Thanks guys. Thanks Uncle bob! I can see all the things you have posted here, And I really appreciate all of it. But I had only one que., How do I prove my enrollment officer that I am good at chess? Should I write a referral? I havent received any certificaltion that prove that I have won a couple of tourneys, and the college rules states that to be an official college chess players, you should win at least ONE tourney with the proof. I dont have anything to show them exp. the trophys, So I really need them, because our chess coach is a national player and If I get into the team, I can learn a lot for my money! Any ideas? Thanks Uncle Bob, my frens envy my diomond membership back here, all because of you! :-D

@ sungolian
you should have called them out at a school board meeting (via email i you wanted). highlight that the principal for a few dollars could have done some bare minimum things but infact ignored your group.

My parents are both teachers for 35 years and I hung out a lot with administrators etc. there are tricks to get wha tyou want :) its just like a job theres a game and you have to know how to play it.
The trophy wasnt the schools. it wasnt school sponsered or supported so the students could have grabbed the trophy and walked out with it and the school would have had no foot to stand on. have the superindent ask the principal why they are keeping something the kids earned but the school didnt support, case closed and the staff looks like jerks.
hit the school board up and watch the principal sweat!
Principals are about politics if you threaten to make them look bad to their boss AND your right they will back off.
The school was lucky and tried to bully them so kudos to calling their bluff. next time they should supported the team. (I coach chess locally and i am very aware of the schools that dont get support and the ones that do)

But dahal32 says his school DID pay for expenses and lodging, so in his case it's clearly the school's option.
Even in the case of the players paying their own way with no support, if they chose to officially represent the school, it matters.
actually you can not officially represent a school unless the school sponsered it. other wise people could run around willy-nilly and claim they represent a school.
We run tournaments and give out team trophies to the players for best school but its all unofficial since the students are doing it. This isnt an activity with state oversight.

So whatdo I do? I need to claim a place in my college team, I need some sort of supportive evidence that i am a good player ?!

for the OP i would talk to the principal or school staff and see what they can do. i think they might be able to give you some of them or at least try to make up a special medal or trophy for your efforts. (they really dont cost much)
because you were part of an official team then it might be harder to justify you taking all the trophies and medals. paying for your transportation and lodging is spendy and many players would be happy with that.
if you wan tto play on a college team just have them look at your tournament results. those should be easy to obtain. if you ask the coach or principal they can perhaps give you a nice recommendation as well

your rating should be also considered or just challenge members to some games. Chess is nice that way,. you beat the players your on the team.
We have a girl locally that is 2000+ USCF and she can basically simul the whole team. She doesnt even bother trying out and they know it.

Thanks guys. I'll be taking the tourney crosstables and the recommendation as you all told. Thanks, the help is much appreciated! As for the simul, I am not so sure, they are all of my tournament level, some even better than me, and wrse, all are positional( Contrasting me, who always is willing to find a sound tactical line :-P ). I get impatient at moments and a simul I will be doing after a get above 2100. ( I am 1900+ now). Gee, thanks guys!
