The aim of this paper is to investigate if there is a difference between the grades of boys and girls inSpanish as a foreign language within the Swedish secondary school and what are some of thereasons for the existence of such differences.For this purpose we have used the following method: we have analyzed the research reportsprepared by the Delegation for gender equality in schools in Sweden (which aim to collect anddisseminate knowledge and stimulate discussion on gender equality in Swedish schools) and wehave collected supposed qualities of girls and boys that might influence their academicperformance; we have made a survey based on those assumptions.This questionnaire study was conducted with 158 students representing 3 secondary schools. Thequestionnaire contains, in addition to the personal information and the grade of each student, 20affirmations which measure students levels of agreement or disagreement (Likert ordinal scale).The results show that girls get better grades than boys. They also show that girls have easier forSpanish as a foreign language than boys; that more girls (36%) than boys (22%) consider to workharder and spend more time at work in the same subject; that when it comes to the instrumentalintrinsic motivation and the gender of the students we have observed that statistically significantcorrelation does exist. The girls would be more motivated than boys by practical factors such as thegrade of access to high school.
