Dear Aspirant,

If the document you received is issued by any Institute recognised by the government only then will it considered valid for admission into college.As per my knowledge it would be  challenging for you to get into a college if your certificate is not valid.So check out the institute issuing you the certificate and if it is government recognised then you are good to go.After ITI Course on clearing English subject the certificate of diploma you get can get you into a good polytechnic institute.Best of luck.Hope your query is resolved.
