1 INTRODUCTION
Educa o s play a cen al ole in shaping s uden lea ning ou comes, and imp o emen s
in educa ion depend hea ily on hei p o essional g ow h (Guskey, 2002). This is
pa icula ly ele an in sus ainabili y educa ion, which aims o p epa e lea ne s o

inc easingly seen as a key d i e o esponsible enginee ing p ac ice (Beagon e al.,
2022), which calls o a shi in bo h he mindse and pedagogy o educa o s (Holmbe g
e al., 2008). This shi equi es engaging s uden s in eal-wo ld p oblem-sol ing and
p omo ing compe encies such as c i ical hinking, in e disciplina y collabo a ion, and
sys ems hinking (Gue a, 2017; Sand i, 2022). Fo educa o s, i demands bo h
commi men and he abili y o design and suppo ans o ma i e lea ning
en i onmen s (Ba h & Rieckmann, 2012; Bü gene & Ba h, 2018; Michel e al., 2020).
In p ac ice, howe e , sus ainabili y in eg a ion is o en d i en by educa o s’ pe sonal

Fu he mo e, many enginee ing educa o s lack o mal aining in hese a eas

s a egies, s uden lea ning, and class oom p ac ices (Mulde e al., 2012; Thü e e
al., 2018).
1.1 Educa o s’ p o essional de elopmen o sus ainabili y educa ion
Educa ing o sus ainabili y equi es educa o s o de elop a wide ange o
compe encies, such as c i ical hinking, communi y pa icipa ion, and emo ion

Tynjälä, 2008). Jus as s uden s a e expec ed o engage in li elong lea ning o na iga e
sus ainabili y challenges, educa o s oo should app oach PD as a con inuous and
li elong jou ney (Bü gene & Ba h, 2018; Ceb ián & Junyen , 2015). Al hough i is
unclea o wha ex en and how he de elopmen o educa o s’ sus ainabili y
compe encies can be e ec i ely in eg a ed in o PD ac i i ies (Ima a & Al inay, 2021),
i is known ha PD ac i i ies a e mos e icien when bound o educa o s’ daily wo k

In uni e si y-based PD p og ams, p o essional lea ning is cons i u ed simul aneously
in he indi idual ac ions and p ac ices o agen ic uni e si y educa o s, he collec i e

1.2 P o essional agency o le e aging PD oppo uni ies
T ans o ming educa ional p ac ices o sus ainabili y equi es agency om
enginee ing educa o s (Mulà e al., 2017). PD oppo uni ies alone a e no su icien :
he ex en o which educa o s can engage wi h and bene i om hem depends on hei

The concep o agency highligh s ha ac o s always ac employing hei en i onmen

agency bo h elies on he belie s ha indi idual educa o s b ing o hei p ac ice and
equi es collec i e de elopmen and conside a ion (Bies a e al., 2015). The e o e, o

(Bies a e al., 2015).
While he alue o PD in sus ainabili y in highe educa ion has been widely
acknowledged (e.g., Fische e al., 2022; Mulà e al., 2017), he e is a gap in
unde s anding educa o s' pe cep ions o PD in educa ing o sus ainabili y wi hin

ques ion is add essed: How do enginee ing educa o s app oach hei p o essional

4 DISCUSSION AND CONCLUSIONS
Th ough in e iews wi h eigh enginee ing educa o s, we ound ha app oaching PD

depending on he su ounding condi ions (Roumbanis Vibe g e al., 2023). Consis en
wi h p e ious indings ha enginee ing educa o s’ pe sonal con ic ions o en d i e

PD in his a ea is s ongly shaped by educa o s’ in insic mo i a ion and p oac i e

The con ibu ions and implica ions o ou indings a e h ee old. Fi s ly, i ad ances

hey play a cen al ole in ansla ing sus ainabili y goals in o meaning ul lea ning

Secondly, he s udy makes a heo e ical con ibu ion by con ex ualizing p o essional

can in o m u u e esea ch on how agency is exe cised o cons ained wi hin a ying

Finally, by ocusing on educa o s al eady ac i e in sus ainabili y educa ion, ou s udy
illus a es agency-d i en p ac ices ha ini ia e and sus ain p o essional lea ning e en
