JSSC Lab Assistant Exam Previous Year Question Papers (PYQs)
Jharkhand Staff Selection Commission (JSSC) going to conduct Jharkhand Laboratory Assistant Competitive Examination (JLACE)- 2023 for the first time on the behalf of Govt of Jharkhand for the recruitment of Laboratory Assistant to a total of 690 vacancies in different laboratories of government's institutions & state owned laboratories.
Although, JSSC had notified regarding the same in the year 2022 as named Jharkhand Laboratory Assistant Competitive Examination (JLACE)- 22022, conducted the exam as well.
But unfortunately, it was cancelled along with dozens of recruitment notifications released by JSSC due to Hon'ble Jharkhand High Court judgement on Domicile Policy based on which these recruitment had to be completed.
And for that reason, the previous year's question paper viz JLACE 2022 has been not released !
Note : You can can go through to other state's Previous Year's Question Papers (PYQs) of Laboratory Assistant/ Lab Technician exams for practice purposes.
