How far is the Lower Saxony support system for financially weak in the laptop / iPatt DUTY to train?

In many schools, the laptop / I Patt duty is already introduced.

But how far is the support system for financially weak in the laptop / iPatt?

The school year has begun and hear nothing.

How is the city?

Of a "duty" is also not to speak here. It is recommended, but not "mandatory".
Most of the schools have their own EDP room area where students are familiar with computer equipment.

Not quite.

I'm in high school, and school is my name

bring your device mit.und this is required.

but I have leg.

No, you can't be obliged, see judgment:
Schools need to provide students with computers
At the job center, a mother applies to finance a homework PC for her son. The court sees the Gymnasium in duty.
A student can't be forced to spend on EDP equipment in the school sector.

Thanks for this link.
However, in § 71 Nds. This is not to be listed as an obligation, so this is not legally recognizable that the trainees can be obliged to the financial expense.

School needs campaign: apply now for school needs at Jobcenter / Sozialamt!
More and more social courts are denouncing job centers for paying for a PC / laptop / tablet computer.
