Graduate students are expected to present their research findings in English to earn their degrees, establish academic careers, and contribute to their field of research. Therefore, acquiring the ability to construct research knowledge in disciplinary-oriented ways at an internationally accepted level can be challenging for doctoral students who come from non-English speaking backgrounds. This study examines how non-native speakers of English assessed their own content knowledge of and abilities in research methods while they were earning their credits and writing their dissertations in English. We aimed to find out:(1) how students assessed their abilities for conducting research and presenting research findings in English at the beginning, (2) at the current point of their PhD studies, and (3) if there were signifi\cant differences between male and female students and across the four years in their studies. The current study is part of a larger research project using a 1 to 6 Likert scale questionnaire. A questionnaire focused on students' specific knowledge and skills concerning: (1) their own research topic, (2) research design and methodology, (3) finding and analyzing the special literature, (4) designing research instruments, (5) formulating research questions, (6) analyzing data, (7) ability to write publishable papers and their dissertation in appropriate academic English. Participants were 255 doctoral students from 49 different countries, using 52 languages in addition to English, studying at 14 Hungarian universities; 125 were female and 127 were male students. The survey was conducted online in the spring of 2022. Students indicated on a 1 to 6 Likert scale their knowledge and abilities at the start of the PhD program and at the current point of their studies. At the start of the program, from among the seven components, the students agreed with the statement that they had a good knowledge of their own research area (M=4.08, SD= 1.36) and they agreed to a less degree (M=3.67, SD=1.50) with the statement that they knew how to write a publishable paper in English. At the current point of their studies, participants agreed to a larger degree with the statements that they had a good knowledge of research and writing in English at a publishable level. An independent-sample t-test found significantly higher scores for male participants both at the start and at the current point of their studies on all seven components, indicating that they were more confident about their abilities. As the descriptive statistics tended to show that students were making progress, a paired samples t-test was conducted, and the result confirmed significant differences (p<.05). To investigate if there were any differences among the students in the four different years (1 st -year, 2 nd -year, 3 rd -year, 4 th -year of PhD program) regarding their perceived abilities of the self-assessed items, one-way ANOVA test was performed, and no significant differences (p>.05) were found among their perceptions. We concluded that students'...
