Naša škola jedna je od pionira kada su u pitanju europski projekti. Prvi ugovor u Hrvatskoj potpisan između Hrvatska agencija za mobilnosti i programe EU (AMPEU) i korisnika dogodio se 2009. godine upravo s I. tehničkom školom Tesla. Radilo se o projektu Partnerstva Leonardo da Vinci (LdV) (projekt: HR-09LdV-MOB-IVT-PTŠT-001). Do 2013. godine škola je provela još tri LdV projekta. 

Od 2014. sudjelujemo u Erasmus+ programima. Do sada su školi bili odobreni KA1 projekti 2014., 2016., 2018., 2021., a od 2023. godine škola je Akreditirana.

Naš najpoznatiji KA2 projekt je CNC Network Train for Europe, koji je 2010. godine proglašen najboljim europskim projektom i osvojio European Charlemagne Youth Prize 2010. U realizaciji ovog, i projekta Train for Europe Reloaded (nastavak prethodnog), dva puta smo posjetili Europski Parlament u Bruxellesu, gdje smo predstavili svoje rezultate. 

Škola je u školskoj godini 2021-2022 dobila priznanje eTwinning škole.

Škola surađuje i s visokoobrazovnim ustanovama. U projektu iDADHOS iz 2021. dvije godine škola je radila s Tehničkim fakultetom Sveučilišta Majka Terezija iz Skopja, a godine 2023. suradnja se nastavila.

Od 2011. I. tehnička škola Tesla ugošćuje učenike i kolege iz Austrije, Finske, Francuske, Njemačke, irske, Italije, Litve, Malte, Norveške, Sjeverne Makedonije, Slovačke i Slovenije. 

Do sada smo ostvarili više od 150 dolaznih mobilnosti.

Our school is one of the pioneers of European projects in Croatia. The first contract in Croatia signed between the Croatian Agency for Mobility and EU Programs (AMPEU), and a user took place in 2009 precisely with the 1st Technical School Tesla, Zagreb. It was a project of the Leonardo da Vinci Partnership (LdV) (project: HR-09LdV-MOB-IVT-PTŠT-001). Till 2013, the school implemented three more LdV projects.

We have participated in Erasmus+ programs since 2014. The school was approved for KA1 projects in 2014, 2016, 2018, and 2021 and has been accredited since 2023.

Our most famous KA2 project is the CNC Network Train for Europe, which was declared the best European project in 2010 and won the European Charlemagne Youth Prize in 2010. To implement this and the Train for Europe Reloaded project (a continuation of the previous one), we visited the European Parliament twice in Brussels, where we presented our results. 

In the 2021-2022 school year, the school was recognized as an eTwinning school.

The school also cooperates with higher education institutions. In the iDADHOS project from 2021, the school worked for two years with the Technical Faculty of the University of Mother Teresa from Skopje, and the cooperation continued in 2023.

Since 2011, the 1st Technical School Tesla has hosted students and colleagues from Austria, Finland, France, Germany, Ireland, Italy, Lithuania, Malta, North Macedonia, Norway, Slovakia and Slovenia. 

So far, we have achieved more than 150 incoming mobilities.
