She is thinking of becoming Muslim, and is asking how she could perform the prayers at school

Praise be to Allaah.

We thank you very much for sending this question to us,
and we urge you to hasten to enter Islam, for Allaah does not accept any other religion.
We also give you the glad tidings of a good future and good life if you enter this
religion.

With regard to your question, we would like to answer it with another
question, by which we do not mean anything silly or foolish:

If a student needs to go to the bathroom urgently during class, what
does he do? The obvious answer is: he asks the teacher for permission and leaves the room.

Praying on time is more important than answering the call of nature. We
would remind you of the following points:

Firstly: the times for prayer in Islam are long, praise be to Allaah.
For example, the time for the Zuhr (midday) prayer – which is the prayer time which
usually comes during the school day) does not end until the time for ‘Asr
(mid-afternoon) prayer begins, so you can pray Zuhr from the time when the sun is at its
zenith until the time when the shadow of an object is equal to its length. This time is a
period of hours, not minutes, so there is bound to be an opportunity to pray within this
time.

Secondly: there are usually breaks between classes; even if the break
is only five minutes, you can make the most of it. There are also breaks for recess and
for lunch during which you could pray. Otherwise you could pray after school is over and
before the time for the prayer ends. Or you could ask the teacher for permission to leave
before the class finishes so that you can go and pray. In some countries there are laws
which enable the followers of different religions to practise the observances of their
faiths at a specific time during the work or school day, so you could avail yourself of
these laws if they exist.

Whatever the case, whoever fears Allaah and does his duty towards Him,
Allaah will show him a way out and make things easier for him. When Allaah knows that a
Muslim is keen to do the obligatory actions, He will help him. Finally, we would like to
thank you once again for your question. We ask Allaah to guide you to the way of truth
sooner rather than later, and to grant you good health and keep you safe and sound. May He
grant you strength and success in your life and keep you safe from all evils.

May Allaah bless our Prophet Muhammad and all his family and
companions.
