Your question is not really clear but I guess you want to easily read/write some field on student model into partner model.
If a Student is always a partner I suggest you to use _inherits = {'res.partner': 'partner_id'}
. Check docs and user/partner example. When you create a user you create a partner too. User model/table will hold only its fields. Another example for this is product.template+product.product.
If you don't need this and you have already a partner related to a student you can add some related fields, like:
fullname = fields.Many2one(related='partner_id.name')
If you don't set it as readonly you are going to write inside partner name.
Last but not least, if partner form is enough for you, just add new tab there, like this:
<record id="partner_mytab_form" model="ir.ui.view">
<field name="name">res.partner.mytab</field>
<field name="model">res.partner</field>
<field name="inherit_id" ref="base.view_partner_form"/>
<field name="arch" type="xml">
<xpath expr="//notebook[last()]" position="inside">
<page string="My tab" name="mytab">
...
</page>
</xpath>
