Is it permissible for my wife to complete her studies in Turkey, while wearing a prescribed uniform that consists of trousers reaching above the knee and a shirt?

The Muslim woman's attire is stipulated to be covering, ample, not tight, and not revealing the body's contours. No specific type of clothing is required, but rather specific conditions.

If the university mandates wearing trousers and a shirt, then a loose garment must be worn over the trousers to cover them. If this is not possible, she may adopt the fatwa of the Assembly of Muslim Jurists of America, which permits wearing trousers if there are clothes covering her body down to or below the knees.

The guidelines for permissible Islamic dress are that it must cover the 'awrah, not be transparent or form-fitting, not be a garment of fame, not involve imitation of men or immoral women, and not have a specific shape or color. The most important thing is that it fulfills the purpose of the hijab by not attracting attention, and that the headscarf covers the head, neck, and chest. If these guidelines are observed, then it is permissible for her to wear it, especially given the necessity of completing her studies.
