Year-End Success Score Calculator

Enter each course’s year grade (or both term grades) and weekly hours to get the year-end success score (yılsonu başarı puanı), weighted by hours, under art. 55 of Türkiye’s Secondary Schools Regulation (high school) or art. 28 of the Primary Schools Regulation (middle school).

How it is calculated

The year-end success score (yılsonu başarı puanı, YBP) is the mean of all of a student’s courses in a school year, weighted by weekly hours; it is not the same as a single course’s “year grade”, the mean of its two term grades. In high school, art. 55(1) of the Secondary Schools Regulation defines it as “the sum of the courses’ weighted scores divided by the sum of their weekly hours”; for a transferred student the new school’s total weekly hours are used. In high school the score is used for: promotion — a student with at most 1 failed course and a score of at least 50 moves up directly (art. 57(1)(b)), with at most 3 failed courses carried over (art. 58(1), as amended on 8 September 2023); the graduation score — the arithmetic mean of the grade 9, 10, 11 and 12 scores (art. 65(1)); breaking ties for valedictorian (art. 64(2)–(3)); ranking transfer applications when there are more than places (art. 38(9)); and, in vocational schools, the grade 9 score when too many choose the same branch (art. 31(2)). In middle school, art. 28(1) of the Primary Schools Regulation uses the same definition and the score is printed on the school record; promotion looks instead at each course’s year grade (the two-term mean, halves rounded up, art. 27(3)(a)): 70.00 or more in Turkish and 50.00 or more in other courses is a pass (art. 21(1)); below that, the class teachers’ board decides whether the student moves up (art. 31(2)(b)). As art. 28(2) words the limit as “the arithmetic mean of the two term grades”, the calculator warns about courses whose mean of 69.5 or 49.5 reaches the mark only by rounding. The mean of the grade 6, 7 and 8 scores is the middle-school success score (OBP, Secondary Schools Regulation art. 4(1)(ii)), used to rank students placed outside an enrolment area they could not get into, and earlier-year grade 8 leavers enrolling (art. 23(2)(a), (f)).

FormulaYBP = Σ(course year grade × weekly hours) ÷ Σ weekly hours · course year grade = (term 1 + term 2) ÷ 2Scores are out of 100. A course’s weight is its weekly hours; its year grade times its hours is its weighted score (high school art. 54, middle school art. 27(4)). Divisions are carried to 4 decimals. In middle school a course’s year grade is rounded to a whole number (halves up, art. 27(3)(a)); in high school it is not rounded.

Choose the school level and enter the courses’ year grades, or both term grades, and their weekly hours in the same order, one per line.
With term grades, each course’s year grade is the arithmetic mean of the two (high school art. 53(1)(a), middle school art. 27(3)(a)).
Each year grade is multiplied by the course’s weekly hours and the weighted scores are added up.
The sum is divided by the total weekly hours, carried to 4 decimals (high school art. 55(1), middle school art. 28(1)).
For high school the tool also shows whether each course is passed (art. 56) and whether the score reaches 50.

Example

High school, eight courses: year grades 78.5, 85, 62, 90, 47, 74, 88, 95 with weekly hours 5, 6, 2, 2, 4, 2, 2, 2. Weighted scores 392.5 + 510 + 124 + 180 + 188 + 148 + 176 + 190 = 1,908.5; total hours 25; YBP = 1,908.5 ÷ 25 = 76.34. One course (47) is failed and the score is over 50, so the student moves up directly (art. 57(1)(b)).

Frequently asked questions

Is the year grade the same as the year-end success score?

No. The year grade is one course’s mean of its first- and second-term grades (high school art. 53(1)(a)). The year-end success score is the mean of all courses’ year grades weighted by weekly hours (art. 55(1)); a course taught 6 hours a week weighs three times as much as a 2-hour one.

What happens if the score is under 50?

In high school a student who passed every course moves up directly whatever the score (art. 57(1)(a)). A student with a failed course needs a score of at least 50 to move up directly or with carried-over courses (arts. 57(1)(b), 58(1)); otherwise the year is repeated (art. 59(1)(a)).

Is there a “45–49 passes with a carried-over course” rule?

Not in the current regulation. A course is passed when the mean of its two term grades is at least 50, or its second-term grade at least 70 (art. 56(1)(a)); carrying courses over depends on how many were failed and on the year-end success score (art. 58(1)). A carried-over course is cleared with at least 50 in its exam (art. 58(4)).

How does the graduation score follow from it?

In high school the graduation score is the arithmetic mean of the grade 9, 10, 11 and 12 year-end success scores, again carried to 4 decimals (art. 65(1)). In middle school the mean of the grade 6, 7 and 8 scores gives the middle-school success score (OBP).

Are honours certificates based on this score?

No. Certificates go by the weighted mean of the term grades, not of the year grades (high school art. 160(1), middle school art. 53(1)); the year-end success score does not replace that.

Why must middle-school grades be whole numbers?

The Primary Schools Regulation rounds halves and more up to the next whole number in the term grade (art. 27(2)(b)) and in the course’s year grade (art. 27(3)(a)), so middle-school course grades are whole numbers; the year-end success score is carried to 4 decimals and not rounded (art. 28(1)).
