The Romanian F (PHI) Online Physics Contest is organized since 2003 by the Alexan- dru Ioan Cuza University of Iasi and the Regional Centre of Excellence. Every year the PHI contest is organized in two stages. At national level the Contest is organized in local centers all over the country for secondary school students of 13 to 19 years old (7-th to 12-th grade). The contest requires solution to different problems speciﬁc for the age and grade level. The assessment items are available on-line for two hours in the same time for students of the same grade. After that, contestants of another grade enter the contest. The rankings for each grade are published and prizes are awarded. Every year more than 2,000 students from more than 60 local centres are involved in the competition. Diplomas are awarded to 25 - 30% of the participants.
The International PHI Contest follows the national one and it is addressed to the Roma- nian PHI contestants that received prizes at the national stage and to any international contestant willing to enrol the contest. Due to curriculum differences the age/grade grouping of students is no longer possible. Instead, there are four sections (topics) of the contest: Mechanics, Thermodynamics and molecular physics, Electricity and mag- netism and Optics. All sections are opened simultaneously and the competitors must solve the problems of a section in 2 hours. The students can freely choose the section there is no age limitation except the fact that the contestant must be a student enrolled in a middle or secondary school. After the contest rankings are published for each section and prizes are awarded.
Organizing the contest is done collaboratively by high school teachers and university staffs. Topics, and difﬁculty of formulated items is decided by a national committee of the competition. The competition committee proposes algorithms for solving and correction scales.
