HCPSS Grade Calculator
Plan your Howard County final grade under HCPSS Policy 8020: combine four quarters and the 10 percent final exam, apply the official rounding rule, and see which exam letter keeps your A or B.
Last updated October 15, 2026
HCPSS course grade
Enter your quarter grades. In a full-credit high school course each quarter is 22.5% and the final exam is 10%.
Quarter grades
For a semester course, delete Quarters 3 and 4 and set the two remaining weights to 45. Leave a quarter blank if it has not ended.
Weights entered: 90%
Graded weight 90% + final 10% = 100%. Most syllabi add up to 100%.

HCPSS grading scale (Policy 8020)
Percent ranges and quality points from HCPSS Policy 8020.
| Letter | Percent | Quality pts |
|---|---|---|
| A | 90+ | 4.0 |
| B | 80 to 89 | 3.0 |
| C | 70 to 79 | 2.0 |
| D | 60 to 69 | 1.0 |
| E | 0 to 59 | 0.0 |
Grades are rounded to the nearest whole percent before the letter is assigned.
Scores round to the nearest whole percent (89.5 becomes 90). The official final grade averages quality points: A 3.50+, B 2.50+, C 1.50+, D 0.75+.
What do I need on the HCPSS final exam?
Policy 8020 sets the final exam at 10% (20% for the Biology and American Government state tests).
Grade you want
Score needed on the final
107.5%
A 90% (A) is out of reach: you would need 107.5% on the final. A perfect 100% gives you 88.75%.
Final 0% gives 78.75%. Final 100% gives 88.75%.
Final score needed for each letter
| Letter | Course grade | Final needed |
|---|---|---|
| A | 90% | Out of reach |
| B | 80% | 7.5% |
| C | 70% | Safe |
| D | 60% | Safe |
What if I score...
Course grade: 86.75% (B)
Estimate only. HCPSS computes the final course grade from quarter and exam letters, and your gradebook is the record.
Howard County Public School System (HCPSS) grades every middle and high school course under one Board policy: Policy 8020, Grading and Reporting. It sets a plain A, B, C, D, E scale with no plus or minus letters, a rule that fractional scores round to the nearest whole number, and a quality-point method for turning four quarter grades and a final exam into a final course grade. The current version took effect on July 1, 2026.
This HCPSS grade calculator handles the percent side: enter your quarter grades, and it applies the 22.5 percent quarter weights, the 10 percent final exam and the rounding rule, then solves for the exam score you need. Because HCPSS actually averages letters, not percents, this page also gives you the quality-point formula, two worked examples and lookup tables that show the exam letter needed for every quarter combination in full-year and semester courses.
The HCPSS Grading Scale Under Policy 8020
| Letter | Percent | Meaning in the policy | Quality points |
|---|---|---|---|
| A | 90 to 100 | Outstanding level of achievement | 4 |
| B | 80 to 89 | High level of achievement | 3 |
| C | 70 to 79 | Satisfactory level of achievement | 2 |
| D | 60 to 69 | Low level of achievement | 1 |
| E | 59 or lower | Failure (no credit for high school courses) | 0 |
HCPSS uses E, not F, for a failing grade, and there are no plus or minus letters at all. A 90 and a 99 are both simply an A worth 4 quality points.
The HCPSS Rounding Rule
Policy 8020 states that fractional scores are rounded to the nearest whole number: when the tenths digit is 5 or more, the score rounds up. The policy's own illustration is that 89.50 percent becomes 90 (an A) while 89.49 stays 89 (a B). The calculator applies the same rule, so its target for an A is really 89.5, and its result card shows the letter after rounding.
Only the tenths digit decides. An 89.46 does not round to 89.5 and then up to 90; it rounds straight to 89. If your gradebook shows two decimals, look at the first one.
How to Use the Calculator
- Full-year (1.0 credit) course: type your four quarter percents. Each row is weighted 22.5, and the final exam weight is 10. Leave a future quarter blank and the tool uses the quarters you have.
- Semester (0.5 credit) course: remove Quarters 3 and 4 and set the two remaining weights to 45. The final stays at 10.
- Biology or American Government: set the final weight to 20 and each quarter to 20, matching the state end-of-course test weighting.
- Pick your target letter. The tool shows the exam percent needed, the grade a 0 or a 100 would leave you with, and the score needed for every letter.
- Then check the quality-point tables below, since your official final grade is computed from letters.
What Goes Into an HCPSS Quarter Grade
Each quarter grade is a percent built from categories your teacher sets within parameters approved by the HCPSS Division of Academics. The implementation procedures and the policy add a few guardrails that shape how much any one assignment can move you:
- Neither the summative category nor the short-term (formative) category may exceed 70 percent of the quarter grade, so no single category can dominate.
- Homework may be graded, but it cannot exceed 10 percent of the total grade.
- Extra credit is not offered in grades 6 to 12, which is why the calculator caps the exam at 100.
- Teachers may allow students to redo work to show at least a satisfactory level of mastery.
- Lateness, absence or discipline may not be used to reduce a grade directly.
To estimate a quarter grade itself, use the rows differently: rename them Summative, Short-term and Homework, type the weights from your course syllabus, and set the final weight to 0. The result card is then your projected quarter percent.
How the Final Course Grade Is Calculated
At the end of the course, each quarter and the final exam are converted to quality points (A 4, B 3, C 2, D 1, E 0) and combined with fixed multipliers. The result is a quality-point average from 0 to 4 that is turned back into a letter.
| Course type | Each quarter | Final exam |
|---|---|---|
| Full-year, 1.0 credit | 22.5% | 10% |
| Semester, 0.5 credit | 45% | 10% |
| Biology, Biology G/T, American Government, American Government Honors | 20% | 20% (state end-of-course test) |
Notice the D cutoff. A plain average would put the D line at 0.50, but HCPSS requires at least 0.75 for a D and for credit. Everything below 0.75 is an E.
The percent planner in the tool follows the same weights: course percent = 0.225 × (Q1 + Q2 + Q3 + Q4) + 0.10 × Exam, and the exam needed = (target - 0.9 × quarter average) ÷ 0.10. Take a student with quarters of 94, 91, 87 and 90: the quarter average is 90.5, so an A (89.5 after rounding) needs (89.5 - 81.45) ÷ 0.10 = 80.5 on the exam. On the official letter method those quarters are A, A, B, A, and a C on the exam already secures the A, as the tables below show. The letter method is the one that counts.
Two Worked Examples
Example 1: Full-Year Course, Two A and Two B Quarters
Priya has quarters of B, A, A and B in a full-year English course. Her quarter quality points add to 3 + 4 + 4 + 3 = 14.
Priya needs an A on the final exam, a 90 or an 89.5 that rounds up, for an A in the course. Any other exam result, even an E, leaves her with a B.
Example 2: Semester Course on the Edge of Credit
Marcus has a C in Quarter 1 and a D in Quarter 2 of a half-credit elective, so his quarter points add to 2 + 1 = 3.
Marcus keeps credit no matter what happens on the exam, and a C or better on the exam lifts the course to a C. No exam result can reach a B, because the 10 percent final cannot cover the gap.
Final Exam Letter Needed for Each Course Grade
Because the exam is only 10 percent, it can move a course grade by at most one letter. These tables apply the official formula to every possible total of quarter quality points. "Safe" means even an E on the exam keeps that grade; "No" means it is out of reach.
| Quarter points (example) | For an A | For a B | For a C | For a D |
|---|---|---|---|---|
| 16 (A, A, A, A) | Safe | Safe | Safe | Safe |
| 15 (A, A, A, B) | C | Safe | Safe | Safe |
| 14 (A, A, B, B) | A | Safe | Safe | Safe |
| 13 (A, B, B, B) | No | Safe | Safe | Safe |
| 11 (B, B, B, C) | No | D | Safe | Safe |
| 10 (B, B, C, C) | No | B | Safe | Safe |
| 9 (B, C, C, C) | No | No | Safe | Safe |
| 6 (C, C, D, D) | No | No | C | Safe |
| 5 (C, D, D, D) | No | No | A | Safe |
| 3 (C, E, D, E) | No | No | No | D |
| 2 (D, E, D, E) | No | No | No | B |
| Quarter points (example) | For an A | For a B | For a C | For a D |
|---|---|---|---|---|
| 8 (A, A) | Safe | Safe | Safe | Safe |
| 7 (A, B) | A | Safe | Safe | Safe |
| 6 (B, B or A, C) | No | Safe | Safe | Safe |
| 5 (B, C) | No | B | Safe | Safe |
| 4 (C, C) | No | No | Safe | Safe |
| 3 (C, D) | No | No | C | Safe |
| 2 (D, D) | No | No | No | Safe |
| 1 (D, E) | No | No | No | B |
Two rows deserve a second look. In a full-year course, 14 points (two A quarters and two B quarters) is the one total where the exam alone decides between an A and a B. In a semester course with one D and one E, the student needs at least a B on the exam just to reach the 0.75 needed for a D and credit, and the passing-quarter rule below must also be met.
Biology and American Government (State Tests)
Biology, Biology G/T, American Government and American Government Honors end with a Maryland end-of-course test, and Policy 8020 gives it far more weight than a regular final: 20 percent, with each quarter also at 20 percent. Officially, you add the quality points for the four quarters and the state test, multiply by 2 and divide by 10, which is the same as a simple average of five letters.
Example: quarters of A, B, B, A and a state test result recorded as a B give (4 + 3 + 3 + 4 + 3) × 2 ÷ 10 = 3.4, a B. If the test result is recorded as an A, the total becomes 3.6, an A. With twice the usual weight, the exam in these courses can decide a letter much more often. The policy does not spell out on this page how a state test score is converted into a letter, so ask the teacher how it will be recorded.
Passing a Course and Earning Credit
- Quality-point average: you need at least 0.75 for a D and credit. An average from 0.50 to 0.74 is still an E.
- Full-year course: you must also pass at least two quarters, with at least one passed quarter in each semester.
- Semester course: you must pass at least one of the two quarters.
- Missing quarters: when a quarter carries an N/A code, the final grade is the average of the remaining quarters and assessment grades.
- Incomplete work: an I code is used when work is unfinished because of excused absences or extenuating circumstances, and it is later converted to a letter grade.
Middle School Final Grades
Middle school courses use the same percent scale and rounding rule, but the final grade is a straight average of marking periods: the sum of four quarter quality points divided by 4 for a full-year course, or two quarters divided by 2 for a semester course, using the same A 3.50, B 2.50, C 1.50 and D 0.75 cutoffs. For a high school credit course taken in middle school, such as Algebra I, the final exam is folded into the fourth quarter grade instead of counting separately. A quarter-long course simply takes the quarter grade as the final grade.
Honors, G/T and AP Weighting in the HCPSS GPA
| Grade | Regular | Honors | AP and G/T |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.0 | 1.0 |
| E | 0 | 0 | 0 |
AP and gifted and talented (G/T) courses add 1.0 quality point per credit and Honors courses add 0.5, but only for grades of A, B or C. Dual enrollment courses receive the weighting of the highest equivalent course HCPSS offers. Cumulative GPA multiplies each final grade's quality points by the course credits and divides by total credits. HCPSS calculates both weighted and unweighted cumulative GPAs at the end of every marking period, and the weighted GPA is used for things like extracurricular eligibility, National Honor Society and honor roll. For a full GPA from your transcript, use the GPA calculator linked below.
Tips for Howard County Students
- Protect your quarter letters. A quarter grade moves 2.25 times as many points as the final exam, so a quarter that rounds up from 89.5 to an A is worth more than any single exam.
- Use the tables to find exams that cannot change your grade, and shift study time to courses sitting on a 14-point total or a 7-point semester total.
- Do not count on extra credit. Policy 8020 does not allow it in grades 6 to 12, so ask about redo opportunities instead.
- Biology and American Government are different: the state test is worth 20 percent and can swing a letter more easily.
- Check your online gradebook for the exact percent to one decimal place. The tenths digit decides rounding.

Frequently asked questions
What is the HCPSS grading scale?
Under Policy 8020, Howard County uses A for 90 to 100 percent, B for 80 to 89, C for 70 to 79, D for 60 to 69 and E for 59 or lower. There are no plus or minus letters, and E replaces F as the failing grade. Each letter carries quality points from 4 for an A down to 0 for an E.
Does HCPSS round grades?
Yes. Policy 8020 says fractional scores are rounded to the nearest whole number, rounding up when the tenths digit is 5 or more. An 89.50 percent becomes a 90 and an A, while an 89.49 rounds down to 89 and stays a B. This calculator applies that rule automatically.
How much is the final exam worth in HCPSS?
In a full-year or semester high school course the final exam counts for 10 percent of the final grade. Each quarter counts 22.5 percent in a full-year course and 45 percent in a semester course. Biology and American Government are the exceptions: the state end-of-course test and each quarter count 20 percent apiece.
How does HCPSS calculate the final grade for a year-long course?
Convert each quarter letter to quality points, multiply each by 2.25, add the quality points for the final exam letter and divide by 10. The result from 0 to 4 becomes a letter: 3.50 or more is an A, 2.50 or more a B, 1.50 or more a C and 0.75 or more a D. Below 0.75 is an E with no credit.
Can the final exam drop my grade in HCPSS?
It can, but only by one letter at most, and often not at all. With quarters of A, A, B and B, an E on the exam drops the average to 3.15, a B. With four A quarters even an E on the exam keeps the course at an A, because the exam is just 10 percent and the quarter points already exceed 3.50.
What is HCPSS Policy 8020?
Policy 8020, Grading and Reporting: Middle and High School, is the Howard County Board of Education rule that sets the grading scale, rounding, final exam weights, quality points, passing requirements and weighted GPA for grades 6 to 12. It was first adopted in 1987, and its current version became effective July 1, 2026, with implementation procedures that guide teachers' gradebooks.
How many quarters do I need to pass in HCPSS?
For a full-year high school course you must pass at least two quarters, including at least one in each semester, and your quality-point average must reach 0.75. For a semester course you must pass at least one of the two quarters. Meeting the average alone is not enough if the passing-quarter requirement is not met.
How are Honors, G/T and AP classes weighted in HCPSS?
AP and G/T courses add 1.0 quality point per credit, so an A is worth 5.0 and a B 4.0. Honors courses add 0.5, making an A 4.5. The bonus applies only to grades of A, B or C; a D is 1.0 in every course type. Dual enrollment courses get the weighting of the highest HCPSS equivalent.
Does HCPSS allow extra credit?
No. Policy 8020 states that extra credit is not offered in grades 6 to 12. Teachers may instead allow students to redo work to show at least satisfactory mastery. Because of this rule, the calculator treats 100 percent as the highest possible final exam score.
Why does the calculator show a different exam score than the letter tables?
The calculator averages percents with the 22.5 and 10 percent weights, while HCPSS averages quality points, so a 90 and a 99 count the same. Near a cutoff the two can disagree. Use the percent result to plan, then check the quality-point tables on this page, since they follow the official method.
