State-Wise Employability of Engineers in India

Originally Published April 16, 2019 by Aspiring Minds, now SHL

Highlights

Tamil Nadu, Andhra Pradesh lag behind in the average quality of talent. States focusing on numbers and not quality, reveals the report. In metros, Delhi again has the best engineers followed by Kolkata and Bangalore.

Summary

India is a diverse country and the diversity extends to the engineering graduates across states. The States Employability report explores the sectoral employability of students from every state.

Technical education in India has scaled over the last decade boasting 1000s of engineering colleges spread across the length and breadth of the country producing over half a million engineering graduates annually.

Aspiring Minds study is based on AMCAT – India’s Largest Employability Test results of over 120,000 Engineers across the country. AMCAT being the leading measure of employability is able to accurately predict the employability of Engineers in various technical roles including IT services, IT Products, KPOs, BPOs, technical support, etc.

The study shows the drop in percentage of employability of engineers across different states for different sectors. Aspiring Minds Research cell has done advanced statistical studies to uncover the core reasons for the dramatic variation in the quality of talent being produced.

IT Services

It is observed that employability in IT services companies is highest in North, followed by East, then West and then South. Delhi and Bihar-Jharkhand emerge as states with the largest percent employability. (See Figure 1) Delhi with its select colleges has emerged as an education hub with high standards of education and attracting the best minds from across the country.

In India, there is a concentration of engineering colleges in a few states. The report looked at the ranking of states considered as ‘engineering hubs’ by employability in the IT Services sector. It is observed that states with more Government colleges as compared to Private colleges fare better on employability.

Variations in Employability across states: Exploring the reasons

Aspiring Minds Research Cell looked into establishing the factors which could explain the dramatics variations in Employability across states. They considered the impact of the state population, size of the state, number of colleges, gender spread, etc as a possible explanation for the same.

Hypothesis: Impact of number of colleges on quality of education

We hypothesize that just the sheer number of engineering colleges in a state influences the percent employability of students in the state. Wherein the number of engineering schools are lower in number, the percent employability is higher and vice-versa. To check this hypothesis we analyzed the relation between the percent employability vs. the number of engineering colleges in each state.

Figure 2: Percent employability correlated to the number of engineering colleges in each state

Interestingly a very high correlation of -0.834 was found between percent IT services employability and the logarithm of the number of colleges in the state. This means that employability falls logarithmically with the increase in the number of colleges in the state. Interestingly, the result is not improved by normalizing the count by population or size of the state. Probably, other variables such as literacy levels, status of education, per capita income, etc. may be useful to get further insight. The simplicity of the result is indeed intriguing and shows how adding more engineering colleges led to a logarithmic fall in the percent of employable engineers. A scatter plot between employability percent and the logarithm of the number of colleges is shown in Figure 2. If we remove the two outliers, the correlation becomes 0.91.

Conclusion

The employability percent decreases with an increase in the number of engineering colleges in a particular state, clearly establishing that opening more engineering colleges shall not solve the problem of the quality of engineers in the country. It is required that rather than opening more engineering colleges, the state needs to concentrate on improving the education standards of current engineering colleges.

Secondly, even though the number of colleges is a major factor in guiding employability in a particular state, it does not explain it completely. For instance, even though Tamil Nadu has a lower number of engineering colleges (~600) as compared to Andhra Pradesh (~750), it has a lower employability percentage (8.33 as compared to 12.73). Similarly, Delhi has more colleges than Bihar, but higher employability. Employability for a state is a complex interplay due to several socio-economic and developmental factors. What is required is a greater thrust on improving the quality of engineering education.

IT Product

With respect to IT product companies (See Figure 11), it may be noted that the trends are different. Whereas IT services’ employability is mainly a function of English and cognitive skills, the skills in computer programming and algorithms also become necessary for IT Product companies. Because of this, the education in college has an equal, if not more impact on IT product employability as compared to the impact of the quality of students when they join the college. This is also evident with the fact that the correlation to the log of the number of students falls to -0.72 from -0.83 in the case of IT services companies. The number of colleges is a suitable proxy for intake quality.

Three states, i.e. Uttarakhand, Kerala, and Chhattisgarh show largely different ranks with respect to employability in IT services and IT product companies. Whereas Kerala and Chhattisgarh better their position with regard to IT Product employability, Uttarakhand climbs down. This is indicative of better education within colleges in Kerala and Chhattisgarh.

BPO

We compared employability across colleges within major metros in the country (see Figure 8 ). We found similar trends to those with regard to employability in states. Delhi (north) shows the highest employability percent followed by Kolkata (East), cities in the West, and the lowest employability figures were observed in colleges in Southern cities.

The skew in employability is quite high, for instance, the IT product employability in Delhi is as high as 1 in every 9 candidates and as low as 1 in every 200 in Chennai. Even though Bengaluru has similar IT Services’ employability as compared to other Southern and Western cities, it shows much higher employability for IT product companies. This indicates that candidates in Bengaluru do much better at computer programming and algorithms even though they show similar English and cognitive skills. This could be better exposure to computer programming either at home, school, or college.

The reason for this skew in employability is explained again by the trend in the number of colleges in each of these cities (See Table 2). The proliferation of engineering colleges in South India and the West has brought down the employability figures. There are way lesser engineering colleges both in Delhi and Kolkata. This is in spite of the fact that the population of Delhi is much more than Southern cities and comparable to that of Mumbai.

Methodology

In this second edition of National Employability Study by Aspiring Minds, this excerpt probes into the employability by states. The study is based on AMCAT scores of more than 120,000 technical graduates engineering and MCA students (in final year) across the country.

AMCAT – India’s largest Employability test was conducted in more than 20 states under proctored environment. AMCAT covers all objective parameters for adjudging employability in the IT/ITeS sector including English Communication, Quantitative skills, problem-solving skills, and Computer Science and Programming skills. Employability figures are based on actual hiring benchmarks on AMCAT scores set by multiple companies in IT/ITeS related sectors. Since the study is based on a standardized aptitude and skill test, not only does it find the employability quotient, but also helps investigate skills that are deficient in a particular group of candidates with regard to different sectors.
