i suppose it depends on your overall score. some schools will only allow you to take them twice, so check in with your schools that you're applying to. if so, either send your best scores or the school will automatically take the best score if you took the teas at the institution and both scores were sent there automatically. typically schools want at least a score of proficient, which is 58.6% and higher (https://www.google.com/search?q=teas+scores&espv=2&biw=1422&bih=736&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj0x8HTgd3KAhXHAxoKHfuEB7UQ_AUIBygC&dpr=0.9#imgrc=8zMSHVCT2LdoCM%3A) i've never heard of a school requiring a certain score in one of the subtests, so that's interesting. you should not be penalized for taking it a third time, it is most likely a matter of the school disregarding the score and taking the better score of the first two attempts.
