Usage tips
Word composition
The word consists of 'Mittel-' (middle) and 'Stufe' (level/stage). So it literally refers to a level in the middle, which fits both meanings.
EXAMPLE
Der Übergang von der Grundschule in die Mittelstufe ist für viele Kinder eine große Veränderung.
The transition from primary school to middle school is a big change for many children.
Context clue
You can tell which meaning is intended from the context. Words like 'Schule' (school), 'Klasse' (grade/class), or 'Fächer' (subjects) point to the school system. Words like 'Sprachkurs' (language course), 'Niveau' (level), or 'Anfänger' (beginner) point to a general learning system.
EXAMPLE
In der Mittelstufe hatte ich Französisch als zweite Fremdsprache.
In middle school, I had French as my second foreign language.
Fixed preposition
To express that someone is at this level, the preposition 'in' with the dative is almost always used: in der Mittelstufe sein (to be in middle school / at the intermediate level).
EXAMPLE
Mein Sohn ist jetzt in der siebten Klasse, also in der Mittelstufe.
My son is now in seventh grade, so he is in middle school.

Mittelstufe vs Oberstufe
upper level
'Oberstufe' and 'Mittelstufe' both describe a level in a school or course system. The difference is how high the level is. The 'Mittelstufe' comes before the Oberstufe and, in school, usually means the grades between elementary school and the upper school. In courses, it is an intermediate level. The 'Oberstufe' is later or more advanced, for example the final school years before the Abitur or a higher course level. The words can be confused because both sound like school sections or learning levels. Remember: 'mittel' is in the middle, while 'ober' is higher up or later.
Mittelstufe
In der Mittelstufe lernen die Schülerinnen und Schüler schon eine zweite Fremdsprache.
In middle school, students already learn a second foreign language.
Oberstufe
Sarah ist in der Oberstufe und bereitet sich auf das Abitur vor.
Sarah is in the upper school and is preparing for the Abitur.
