The main objective of this paper is to analyze the types and levels of Anxiety and Academic Achievement according to age, gender, culture and socioeconomic and cultural, as well as the relationships between both variables. We focused on 811 participants 71.6% of whom were Muslims and 28.4% Christian; 46.1% male and 53.9% female. The techniques used in this survey were the STAIC (Spielberger, 2001) as well as the students’ grades. The results reflect medium-low levels in Anxiety and medium levels in Achievement. Anxiety is influenced by age, gender, culture and status. Academic Achievement is influenced by age, culture and socioeconomic and cultural. There is no statistically significant relationship between Anxiety and Achievement, except in Mathematics, increasing as the Anxiety scores are lower.Este trabajo tiene como objetivo fundamental analizar la ansiedad y el rendimiento académico, sus tipos y niveles en función de edad, género, cultura y estrato socioeconómico, así como contemplar las relaciones entre ambas.
