# Platform Overview

> Understand how the Lena platform works — the four apps, school types, user roles, and how everything connects.

Lena is an education platform designed for schools across Africa. It connects
students, teachers, and school administrators through a set of purpose-built
apps that work together seamlessly.

## The four apps

<CardGroup cols={2}>
  <Card title="Student App" icon="mobile-screen" href="https://student.lena.africa">
    Available on mobile and web. Students use this app to access courses,
    view study materials, submit assignments, take quizzes, participate in
    discussions, and track their grades.
  </Card>

  <Card title="Teacher App" icon="mobile-screen" href="https://teacher.lena.africa">
    Available on mobile (iOS and Android) and web. Teachers create and
    manage courses, upload materials, build assignments and quizzes, grade
    student work, and communicate with students.
  </Card>

  <Card title="School Admin App" icon="desktop" href="https://school.lena.africa">
    Web-based dashboard for school administrators. Manage your school's
    structure, add students and teachers, create courses, configure academic
    sessions, and oversee CBT exams.
  </Card>

  <Card title="CBT App" icon="desktop" href="https://cbt.lena.africa">

<Tip>
  All four apps share the same Lena account. Sign up once, and you can log in
  to any app with the same credentials.

## School types

When a school is created on Lena, the administrator chooses one of three school
types. This determines the academic structure available:

<Tabs>
  <Tab title="K-12 Schools">
    K-12 schools use a **grades and arms** structure:

    * **Grades** represent class levels (e.g., JSS 1, JSS 2, SS 1, SS 2, Primary 1)
    * **Arms** are subdivisions within a grade (e.g., Arm A, Arm B, Science Arm, Arts Arm)
    * **Terms** divide the academic year (e.g., First Term, Second Term, Third Term)

    Students are assigned to a specific grade and arm. Teachers create courses and assign them to grades.
  </Tab>

  <Tab title="Universities">
    Universities use a **faculties and departments** structure:

    * **Faculties** are broad academic divisions (e.g., Faculty of Science, Faculty of Arts)
    * **Departments** sit within faculties (e.g., Computer Science, Mathematics, English)
    * **Levels** indicate a student's year of study (e.g., 100 Level, 200 Level)
    * **Semesters** divide the academic year (e.g., First Semester, Second Semester)

    Students have a faculty, department, level, and matriculation number. Teachers (called "Lecturers" in this context) create courses within their departments.
  </Tab>

  <Tab title="Other">
    The "Other" school type is a flexible option for non-traditional institutions — training centers, coaching academies, online schools, and similar organizations. It provides a simplified structure without the rigid grade/faculty hierarchy.
  </Tab>
</Tabs>

<Warning>
  The school type is set during school creation and cannot be changed
  afterward.
</Warning>

## User roles

Every Lena user has a **role** within each school they belong to. You can have
different roles at different schools.

### Students

Students join courses using entry codes, access study materials, submit
assignments, take quizzes and CBT exams, participate in discussions, and track
their grades.

### Teachers

Teachers create and manage courses, upload study materials, build assignments
and quizzes, grade student work, post announcements, create discussion threads,
and manage CBT exams.

Teacher sub-roles include: | Sub-role | Description | |----------|-------------|
\| **Teacher** | Standard teacher role (K-12 context) | | **Lecturer** | Standard
teacher role (university context) | | **Assistant** | Assists with course
management | | **Student Assistant** | A student who helps manage a course |

### School Admins

School administrators manage the institution itself. They have access to the
School Admin app at [school.lena.africa](https://school.lena.africa).

Admin sub-roles include: | Sub-role | Permissions | |----------|-------------| |
**Super Admin** | Full access to all school operations | | **Academic Admin** |
Academic structure, courses, and user management | | **Non-Academic Admin** |
Non-academic operations |

## How it all connects

Here's how the different parts of Lena work together:

1. A **School Admin** creates a school, sets up the academic structure (grades
   or faculties), and adds users
2. A **Teacher** creates courses within the school and shares entry codes with
   students
3. **Students** join courses using entry codes and access all the learning
   content
4. When it's exam time, teachers create **CBT exams** that students take through
   the dedicated CBT app
5. Everyone can track progress through **grades**, which are automatically
   calculated based on assignment and quiz scores

## Multi-school support

Lena supports belonging to multiple schools with a single account. For example,
a teacher could teach at two different schools, or a student could be enrolled
at a school and a coaching center simultaneously.

Each school you belong to has its own **school profile** with role-specific
information. You can switch between school profiles at any time. Learn more in
[School Profiles](/general/school-profiles).
