The tuition fee for a crash course in interior design training depends on many factors, such as the length of the course, the qualifications of teachers, the reputation of the school or institution, and so on. Therefore, it is difficult to give an exact figure.

Generally speaking, the tuition fee for a crash course in interior design training may be between thousands and tens of thousands of dollars. Some high-end design schools or institutions may charge higher fees, while some short-term basic courses may be relatively cheaper. In addition, some institutions may offer installment payment or loan options to help students share tuition fees.

If you are interested in the tuition fee of the crash course of interior design training, I suggest you go to the local design school or training institution to investigate and find out their course content and tuition fee. You can also search for relevant information online, or consult some interior designers for more advice and guidance.

In addition, I want to remind you that although interior design is a promising industry, learning interior design is not an easy task. Need to have a certain foundation of art and design, as well as solid knowledge of technology and materials. Therefore, when choosing a crash course in interior design training, you must carefully consider your interests and abilities and choose a course that suits you.
