This research aims to identify and classify errors and causes of errors in using basic English grammar among students of Bachelor of Arts program in English, Faculty of Humanities and Social Sciences, Valaya Alongkorn Rajabhat University under Royal Patronage, Pathum Thani Province. This research is a quantitative study. The scope of data collection was limited to 3 sets of 40 questions each, extracted from TOEFL ITP (Test of English as a Foreign Language-Institutional Testing Program), a standardized English proficiency test in a multiple-choice format. The results showed that the most common errors found was using the correct tense with time expressions, followed by positioning prepositions in a sentence, positioning adjectives and adverbs in the sentence, distinguishing countable and uncountable nouns, and using a parallel structure with paired conjunctions, respectively. Two types of common errors found in almost the same percentage were using clause and subject connectors and correct ordering of subjects and verbs. The least common error found was using adverbs to connect sentences. From the analysis results, it was found that the errors occurred from many factors, including language transfer and overgeneralization of the target language grammar.
