天津大学深圳学院本科生的课程成绩采用国际通行的等级制成绩并与香港理工大学的“十二等级制”成绩一致，同时把“十二等级制”成绩对应到天津大学规定的“绩点”和百分制成绩的分数段。
| 等级 | 百分制分数 | 绩点 |
| A+ | 100-95 | 4.0 |
| A | 94-90 | 4.0 |
| A- | 89-85 | 3.7 |
| B+ | 84-82 | 3.3 |
| B | 81-78 | 3.0 |
| B- | 77-75 | 2.7 |
| C+ | 74-72 | 2.3 |
| C | 71-68 | 2.0 |
| C- | 67-64 | 1.5 |
| D+ | 63-62 | 1.0 |
| D | 61-60 | 1.0 |
F
| 59-0 | 0.0 |
注：F为科目不及格等级，其他等级（D至A+）均为科目及格等级。如果科目不及格，将无法获得学分。计算成绩排名时，按照等级制成绩对应的百分制成绩分数段的最高分数计算。
根据《天津大学本科生学籍管理办法》和《天津大学学生考试工作规定》，评价学生学习质量采用“绩点制”，绩点数的计算方法为：
一门课的绩点数=学分数×绩点
平均绩点=所学课程绩点数之和÷所学课程学分数之和
本说明仅作为帮助理解等级制成绩和绩点的解释，具体执行以官方文件为准。
