When your child's test scores improve, it makes sense as a parent to write a few short messages of encouragement to your child. Here are some short message suggestions for your reference:
1.Congratulations on your progress, it's the result of your hard work. Keep it up and you'll get better and better!
2.I am very relieved and proud to see your progress. Keep working hard and confident and believe that you will achieve more!
3.I am very happy with your progress and it is a reward for your hard work. I hope you continue to maintain this state and keep improving yourself!
4.Your grades have improved, and this is the result of your continuous efforts. Keep up the momentum and you'll be able to achieve even better!
5.Congratulations on your progress, and it's a reward for your perseverance. I believe you will continue to keep this progress and achieve greater goals!
These messages are short and concise, which can express parents' encouragement and support for their children, and can also motivate children to continue to work hard and achieve better results. Remember to focus on affirming and praising your child's efforts and progress in your message, so that your child can feel his own growth and progress, so that he can have more confidence and motivation to meet future challenges.
