This article compares previous results with those from a recent research on bullying  among school children in Costa Rica to determine if this undesirable behavior had increased in  the country. We selected, intentionally, 34 groups of elementary students, third through sixth  grade, ages 8 through 15 years old, from different schools. The total of students participating was 1155. They were given the same survey and once the tally was converted to percentages of responses, they were compared with results obtained from previous studies done in different regions of Costa Rica by Cabezas (2007, 2010), under similar circumstances. This new results show  significant differences that make us presume that bullying is a reality and is increasing in Costa  Rican schools
